Ignore sqla-migrate inspect.getargspec deprecation warnings on py36
Ignore sqla-migrate inspect.getargspec deprecation warnings on py36

The 'message' argument is a regex so you need to escape brackets and the
likes. Strange that this worked on py27.

This was coincidentally fixed by Ib9f735216773224f91ac7f49fbe2eee119670872
in Train but this change is backportable while that one is not.
