Previously `_` was monkeypatched in tests/core.py and bin/keystone-*. This meant that if a developer was not running the tests exactly as the documentation described they would not work. Even importing certain modules in a interactive Python interpreter would fail unless keystone.tests was imported first. Monkeypatching was removed and explicit import for `_` was added.
