    location: Update available accuracy on max accuracy changing
    
    We translate 'On' to available accuracy level but if available accuracy
    level later changes, we don't update available accuracy level accordingly
    and hence limit the accuracy of apps.
    
    E.g if available accuracy level is 'city' and geolocation is enabled,
    the max accuracy level would be 'city' and apps can't get higher than
    that. Now if user plugs in GPS, the available accuracy level will change
    to 'exact' but without this patch max accuracy level will remain to be
    'city' and apps will not be able to use the GPS.
