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 'PYTEST_VERSION' is needed to be even more strict when we're running pytests, which allows us to catch outdated Blender properties in time.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.
```
