commit: clear mergestate also with --amend (issue6304)

The `hg commit --amend` uses the in-memory code, which naturally
doesn't touch the merge state (well, it shouldn't anyway; I think I've
fixed bugs in that area recently). We therefore need to clear the
mergestate after calling `repo.commitctx()` since we expect that from
`hg commit --amend`.

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