tests: show that interactive shelve can leave the repo with a merge state

If part of a file is shelved (as we already do in a test), there will
be an unfinished merge state left after `hg shelve` finishes. There
should never be a merge conflict and there should never be a reason
that the user would like to re-resolve conflicts, so we should clear
that state (see next patch).

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