Title: Make ocr-numbers exercise compatible with Python3

The `assertRaises`-context-assertions had necessarily to be changed because this syntax was removed with Python3. They were replaced by simple `assertRaises` in compliance with https://github.com/exercism/xpython/issues/30. A comment in the test suite specifies that raised exceptions must include error messages.

The other changes are formatting changes introduced by a run of autopep8.
