test-revlog: test a repository that contains a diff against nullrev

We are witnessing a crash in the rust code, so we lets make sure this case is
tested.

#!/bin/bash
#
# Make sure to patch mercurial to create the delta against nullrev
#          if deltainfo is None:
#-             deltainfo = self._fullsnapshotinfo(fh, revinfo, target_rev)
#+             deltainfo = self._builddeltainfo(revinfo, nullrev, fh)
