Bugfix : Users with no preference wrongly see expanded

The default state gets set to VOLUME_OVERLAY_SINGLE

This then prevents the if (choosenStyle == -1) from being triggered

Then in the ChangeOverlayStyle method, the early return is hit,
so the MORE button and Devider is never Hidden.

This only happens if a user has not got a preference stored in the settings.db
