Project data sometimes not saved correctly

[SkepticRaven]

Symptom:
Sometimes in a project with multiple behaviors, a behavior will disappear from the menus.

Solution:
Until this is patched, you can simply add a new behavior with exactly the same name. Existing annotations should re-appear.

Details:
As suggested above, annotations are not affected, only project.json.
This was likely introduced at some point when I was modifying the project settings in the v0.17.1 tag.
I suspect the exact issue is a missing UI socket that should be triggering updates to the project.json file.
There may be other buttons that are not adequately modifying classifier states (other have reported feature subsetting flags not being correctly changed).
