Felix Geyer 721bec9794 Make sure we don't lock the database while a dialog is open.

- the user is picking out a file to save the database as
- a dialog asking the user to save/discard/cancel the current database
  changes is active

It is dangerous to lock the databases while these actions are still
in progress.
