Title: remove branch from Repo step's source data

Including the manifest branch name makes switching branches trigger a
clobber. Repo tool takes care of cleaning up (or failing if not
possible) the tree when switching manifest branches without clobbering
what already existed. That behavior is much more eficient and equally
correct.
