Removed print services not fully cleaned up.

1. When a print services is removed it is removed from the
   installed and enabled services but not from the active
   ones while it should.

2. If a package has more than one print service (very rare
   but possible) we are executing the "make everything right"
   code for each of them which is not very optimal.
