Properties remain in model browser after deletion #3557
Description
Describe the bug
When an association is removed, properties owned (or at least a member) of the class they refer to are still present in the model browser.
It looks like removal from the model works fine: when the model is reloaded, the properties no longer show
To Reproduce
Steps to reproduce the behavior:
- create 2 classes
- create an association and make both end navigable
- remove the association
- Note that the properties are still visible in the model browser. Interacting with those elements raises exceptions.
Selecting the "ghost" element raises an exception:

Expected behavior
The Model Browser should represent the actual state of the model.
