Android: Restore the default QSettings path to the .config directory

Browse Source 
After 140ca89a3c commit, the path of the
QSettings default file location changed. That caused the problem with
updating the app (old settings file is not used anymore). That is why we
should still use old (.config) directory for QSettings file if the file
exists.

Pick-to: 6.2 6.5 6.6
Fixes: QTBUG-109405
Fixes: QTBUG-109369
