rebase: add test to demonstrate an issue in dry-run

In dry-run mode, the case when there is nothing to rebase
is not handled correctly. Added test show that it try to
abort a rebase while there is no rebase in progress.

This will be fixed in next patch.

Differential Revision: https://phab.mercurial-scm.org/D9658

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