Add NoAssertions cop

Fixes #123

I posted a question in the issue that I think still needs to be addressed:

Another thing to keep in mind is that the assertion may happen in a method called by the test, in which case it wouldn't be possible to catch through static analysis.

I don't have any good ideas for this, sorry for not addressing it directly. The MultipleAssertions cop would have the same problem.

I guess this is where rubocop:disable comes in. It doesn't feel like great practice to me to have no assertions inside your test.
