Sort the repr of PolyDict by its dict keys

[embray]

This is one of those cases where a class has a dict representation embedded in its repr, so where IPython would normally pprint the plain dict it does not pprint the embedded dict.

The PolyDict class is only used internally so this should be a low impact change, but that enhances its testability (especially in moving to Python 3).

Huh, thanks for fixing those additional tests. Those must be new since I first made this change (which was actually quite a few weeks ago now).
