histedit: resolve revs before evaluating %ld revset

We want to stop relying on basectx.__int__. That means we can't
use the %ld revset operator with an iterable of contexts. So
we expand an iterable of contexts into a list of revs before calling
into the revset.

Perhaps it would be worthwhile to add a revset format operator
that recognizes context instances so we can just pass contexts
as revset arguments?

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