Description and Context
This bug impacted unsafe saves
When auto save after every change was enabled, an unsafe save to a location that has become unavailable (eg, dismount veracrypt drive), the database modified signal would continually activate a save action that failed. This caused an infinite loop.
When auto-save on exit was enabled, the database tab and the application itself refused to close if saving failed for whatever reason.
The fixes in this commit prevent both of these scenarios from occurring
