Fix filtering for By Album view in Music Sections.

This is somewhat broken in the skin right now. Pushing to get Seb to
look at it.
Revert the changes to primaryFilterActivated.

The primaryFilterActivated property will be set to “yes” when we don’t
have any secondaryFilters to show. In Movie Sections this means that we
have anything but the “All” primary filter marked. In Music sections
this means that we have Recently Added marked. Artists/Albums are still
able to be filtered.
Fix Recently Added in Music sections.

We need to make sure to not add /all when we are dealing with other
primary filters.
Add PlexPreplay to ALBUM/TRACK level.

This shows us that we are not in the top level.
