Avoid some unnecessary effort in compuing "affected"

Browse Source 
* A package being removed is *not* affected
   - It will just be filtered out later in "check_packages"
 * Since all transitive reverse dependencies will be added to
   "affected" at the end of the method, there is no reason to
   find the immediate set of reverse dependencies of a package
   if the package is added itself as well.
