Mock out SES for py.test integration tests
Mock out SES for py.test integration tests

This is a hack, but will should fix the immediate problem of integration tests
sending out email. Previously, we had fixed if a user ran `runTests.py`
directly, but if using `py.test`, tests outside the scope of `runTests` will
be auto-discovered (and not use the mock)
