    placesview: fix open action for locations without a mount or volume
    
    In the "Other Locations" view, locations can be opened from the context menu
    based on their mount or volume. However, some locations, like "Computer", do not
    have either of those so they cannot be opened from the context menu. In order to
    fix this, the file associated with the location can be used as well.
