Fix missing IFC undo for all activate drawing operations

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.
```
