test: test folder renames

Browse source 
In [1] Mark Walters reported a problem with messages being removed
from the database when the parent directory was renamed. Jani Nikula
proposed [2] these tests but observed

   This test is not suitable for merging since it's not deterministic.

After applying Jani's patch [3], the tests now pass deterministically,
and could usefully act as regression tests.
