phab-refresh: do not error out when the stack is empty
Actually, empty stack is easier to get than I expected (and harmless). When a
stack is publish, heptapod will detect the even, empty the stack (triggering CI)
and "forgetting" the branch afterward.
So we stop returning as error in this case.

bzr >= 1.4. Merge it back in test-convert-bzr-directories once
this version becomes mainstream.
