Fix test states for `test=True`

The states for testing without changes were always doing `result = None` on `test=True` runs.  This implies that changes would be made if the state were running in non test mode.  Change these to `True` and `False` for success/failure respectively.

Also remove some weird slang.  Probably don't need the phrase `Yo dawg` in our state output.
