Remove a special case where the appengine-pipeline generate task_target

improperly when module == 'default'.

The sepecial case is causing a failure after a recent changes to
dev_appserver (Taskqueue 'target' made compatible with dev_appserver)
when taskqueue.py tries to parse module name.

For background see cl/126706214.
