clean up some target delegation cases

This patch cleans up some minor inconsistencies in target delegation.
It's primary purpose is to avoid confusion in the code.  A few spots
were checking the "beneath" target; however this can only be NULL for
the dummy target, so such tests are not needed.  Some other spots were
iterating over the beneath targets, looking for a method
implementation.  This is not needed for methods handled by
make-target-delegates, as there is always an implementation.
