phases: avoid a potentially costly dictionary interation in some case

If we retract for the draft phase, there is not non-public item to be retracted
and we can skip this part. This part is was apparently super costly thanks to
Python.

On mozilla-try-2019-02-18, a perf::unbundle call with a 10 000 changesets
bundle gives give use the following timing.

e57d4b868a3e:     4.6 seconds
ac1c75188440:   102.5 seconds
this-changeset:  30.0 seconds

So we recovered about ⅔ of the regression, the next changeset will give us the
rest back.
