database use after close

[kieranlblack]

Describe the bug
Closed database checks still not right. I'm still getting a use after close error:

Traceback (most recent call last):

To Reproduce

1. open add new card window
2. fill in hanzi field
3. click close on main window
4. trigger fill with any sort of event on the add window
5. see error above

Probably because the handler for closing is being called even though the add window is still open. Might be an Anki issue tbh but we can at least account for it.

Yeah it seems like the profile_will_close hooks is triggered when the main window is closed, which leads to issues when other windows are open. I don't think that is intended behaviour.
