Remove compact PhotoActionPopup's "Remove Photo"

The "Remove Photo" option was causing problems. I was able to do the
following:
1) Remove a photo from a read only raw contact
2) Remove a single photo from a contact with multiple photos. This
   removes the current photo and arbitrarily picks another photo
   to be the current photo

Killing the "Remove Photo" option removes these problems and was
suggested by UX a couple months ago.
