revsets: passing a set to baseset() is not wrong

Since 69c6e9623bdc (revset: force ascending order for baseset
initialized from a set, 2016-04-04), it is safe to pass a revset to a
baseset.

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