clean: check that there are no conflicts after

As noted by Pulkit, there should never be any conflicts after doing a
clean update, so `hg.clean()` should never return `True`. Let's check
that assertion instead to clarify the code. The callers will now get a
`None` instead of a `False` returned, but that should be fine (both
result in a 0 exit status).

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
