Drawings are now activated in a bit different way - not by the camera button located above the drawings list, but by using the camera indicator next to each drawing. Which allows do change active drawing very quickly. All activation options (shift+, alt+) are also available from this indicator.

Otherwise errors were passing silently (just console errors) and remained unfixed. 'PYTEST_VERSION' is needed to be even more strict when we're running pytests, which allows us to catch outdated Blender properties in time.

Very dangerous bug that could create a situation when .blend will go out of sync with IFC leading to unpredictable issues.
Example issue:
1. Create a drawing and activate it.
2. Create a grid.
3. Activate the drawing again.
4. Undoing just drawing activation here would work fine - annotations would be still floating in IFC without objects, but that would be fixed on the next drawing activation
To make it more dangerous undo grid creation. Then you'll get the traceback similar to the one below. The most dangerous part of it, that user won't see an error, it will just pop up in the system console silently.
```

Noticed fixing #6670 that though example project in this issue had camera named "PERSPECTIVE" but it was saved to IFC as orthogonal and there is no straightforward way to change it, besides changing Blender camera props and updating representation.

It's kind of exposed to UI now, but there's still bunch of issues with it to address.
Similar issue to 82f25f5
Basically matrix is a little bit different every time you activate drawing even if user made no changes to camera position. My guess is basically all float values stored by Blender somewhere deep as float32 but when you access matrix world, Blender converts them to Python floats (which are float64) and some garbage values introduced along the way creating this noise.
To make it possible to run the tests with PYTEST_DISABLE_PLUGIN_AUTOLOAD set, which is very useful if you don't want to start Blender anytime you run any tests on your system.
Traceback errors give users an impression that some broke and maybe project now is in some invalid state and they should ctrl-z immediately, error reports are much more friendly.
