No test on NEVER_UNPERMITTED_PARAMS

[levsero]

There is no test that ensures that the params in NEVER_UNPERMITTED_PARAMS ("controller", "action") are excluded from the permitted params.

If you remove both mentions on NEVER_UNPERMITTED_PARAMS in parameters.rb all tests still pass.

p.s first time opening a git issue, please feel free to correct me in all aspects.

Yes. I think you are correct. Feel free to write tests for it.
