Elliot Winkler e11891e818 Rewrite the tests for #permit
* Use `permit` directly instead of manually building the matcher
* Some tests were being tested by calling #matches? directly when they
  shouldn't have been, and some tests were duplicated
* Rename helper methods that define controllers to express intent better
* Don't make a global class (SimulatedError), keep the class local to
  the example group
* Use lambdas for that use `raise_error`
