Unlinking was using copied object name for the unlinked object instead of the original one.
So it worked like Cube -> IfcWall/Cube -> Cube.001 and bim test was failing:
FAILED test/bim/test_feature.py::test_unlink_object - AssertionError: The object "Cube" does not exist
1) Explicitly set empty ifc project not to load demo library - was still loading because it was using my default scene which caused errors.
2) typo in dimension check assertion message
Fixed error that was occuring if you try to import .ifc file where spatial element contains only grid and will use advanced mode, filter mode = "IFC Class" and check "Filter Spatial Elements".
Error occured because spatial element was filtered out but then when ifc grid was created and importer to find a spatial element based collection for the grid it couldn't find it.
Traceback:

In ifc2x3 IfcProject is not IfcContext because there is no IfcContext in ifc2x3 and it was causing the error below on .ifc import with filtered spatial elements.
Also added small refactor

Now changing style type should be a bit more intuitive - previously there were no button and it wasn't possible to change style type for all selected objects / changing style type for the entire scene were hidden in N-panel Miscellaneous section.
Now it also able to change style type for all blender materials, even the ones that don't have any objects using them (wasn't possible before 7c0c934b4)
`ifcmerge` is asymmetrical. When both branches have new entities, either
local or remote step Ids need to be renumbered to resolve the merge
conflict.
If the remote branch is 'origin/main' or 'main' we preserve remote Ids,
otherwise we preserve local Ids.
This should support a workflow where a local 'main' branch is kept
pristine, but other local branches are treated as disposable; it should
also support a workflow where multiple authors access a shared 'origin'.
Unfortunately I couldn't find a way to make it work with areas that user created during current blender session. But new areas will have this feature too after blender restart
also found a way to switch shade graph for two materials without juggling active materials and active objects - it was necessary to make it work on import without adding temporary active object
Procedure to merge a pull request would be: Add Remote, select the added
remote in the pull-down, Fetch from remote, select the added remote
branch in the pull-down, Merge, delete remote
Added support for external blender styles that will be saved to ifc.
What it basically means that you can append material from external .blend file as a style that can be loaded in your blender material anytime.
1) External style can be added in Material Tab

Note that you select material name at the right side of file selecting panel:

2) After adding external style you can switch between external and other surface styles:

3) There is also option to switch styles to External for all objects in the scene:

Some other changes:
- some ui adjustments
- moved functions that create blender shaders to tool.Loader (they also reset shader graph now so it's possible to use them on non-default blender materials)
- some new tools for copying node graph from one material to another, appending data blocks
- new operator for browsing external styles can be reused later to append other data blocks
