record-store: Handle old and new database locations gracefully

Browse source 
Because we rename the project and binaries to 'gnome-calls' we want
to make sure that the call history is preserved by doing the following:
If there is an old directory '~/.local/share/calls' try to rename it to
'gnome-calls'. Use new location if it succeeds and fall back to old location if it failed.
