add test case for 403 error on PUT

Hi, i receive a `403` error by Eve as response of a `PUT` request which looks correct, and where the settings should apparently allow it. I tried to replicate the use case with the Eve test suite, and indeed my test is failing there. I am not an expert of the test suite, i collected this quickly, so this could be a false positive.

This pull request is not intended to be merged, but just to show the failing test
