3348: raise error on unknown arguments to raises

[jeffreyrack]

Per #3348, I've gone ahead and updated pytest.raises to raise a TypeError if an invalid keyword argument is passed.

In addition, I fixed an issue of a test case in pytest that was passing an invalid keyword argument to pytest.raises.

fabulous execution and nice find 👍

since you use pop, please use if kwargs as the condition as that sufficient for boolean context

Really looking forward to dropping Python 2 support so we don't have to do kwargs handling by hand 😉

Thanks @jeffreyrack!

Done @RonnyPfannschmidt's suggestion of using if kwargs and updated CHANGELOG slightly (did I ever say I love being able to edit files directly in GH's interface? 😉)

Definitely! Perhaps next year with 4.0? 🤞
