if you switch ifc_class then relating_type_id can become invalid and we wasn't taking it into account
Also fixed bunch of warning like `pyrna_enum_to_py: current value '17' matches no enum in 'BIMModelProperties', '', 'relating_type_id'`` when some ifc_class has N related types and then you switch to other ifc_class that has less than N related types.
This reverts commit 4bc987924d since there was some unintentional changes.
Now when you use select_type in object properties - ifc class and related type gets selected in the BIM Tool - https://i.imgur.com/drIHYDz.png#3318
Basically if current mesh curve is non consequtive we handle it in similar way to b03c4da7b - convert it to curves using Blender and then save them to ifc.
The advantage is that it creates less curves in ifc because mesh method wasn't able to detect separate curves correctly if vertex order was messed up (usually it is) and it would create separate curve for each curve segment.
I've also replaced figuring vertex duplicates with `bmesh.ops.remove_doubles` manually with `bmesh.ops.remove_doubles` and it's now much faster. In some cases because of the manual calculations it was taking too long - in #3233 Ryan mentiones that it freezes blender, it wasn't really freezing Blender but to finish calculations it would take 10 minutes.
It was a bit confusing UX since when you finish editing arbitrary profile path the data is already saved in ifc but you were still in editing profile properties
IfcRelConnectsElements type of connection wasn't handled properly resulting in errors.
Now you should be able to see connections for connected slabs, walls etc - https://i.imgur.com/LpFBKBC.png

While these actions are short in the backend--taking about 0.01 seconds to run--the Blender UI lags a lot leading to 2-3 second pauses because of the "refresh_brick_viewer" function being slow. This should be investigated.
- Turns out, you need the keyword "graph=" in graph_at() to actually select a graph of that name from the collection, otherwise it just returns the entire collection, so I changed that, which correctly isolates the project from the collection for serialization now.
- With this same change, I opted turn BrickStore.VersionedGraphCollection simply into BrickStore.graph and create a new BrickStore.get_project() to return the isolated graph. - This meant I should remove the reload_graph() function because I was actually just loading the entire collection into it still, and its functionality breaks when it isn't the entire collection
All the right code seems to be in place, but it seems the package won't go through with the serialize function because of read/write permissions (ERRNO 13)
