dispatch bugfix: too much debug code left

While I was debugging, I used localhost for ready worker address,
thinking that the problem might be that the dispatcher was using
u'localhost' instead of 'localhost'...  That wasn't the problem,
but the commented-out actual line, and the line that hard-coded
localhost for all ready worker addresses, were committed anyways.
Merge branch 'bugfix' into develop--Finished bugfix.
