Subject: [PATCH 092/124] Geary.Controller: Migrate release config if needed
If the current config directory is empty, go looking for config data
in other well known locations and if found, copy it all across from
the most recently modified directory.
This supports migrating config from non-Flatpak to Flatpak locations,
and release config to devel profile locations.
Fixes #326
