Fix broken tests

Commit f213668 broke test_create_job_nowait because it changed the job
manifest (by changing the rsync script). We resolve this by introducing
`equalish()` function in `tests/helpers.py` that can make approximate
comparisons between complex objects; we use this to ignore the content of
the `command` key in the job definition.
