[YouTube] Remove YoutubeSearchExtractorTest.Suggestion

Searches are now always corrected by YouTube, which provides a way to still search for the input term. In this case, a "Did you mean" message will be shown. The extractor doesn't support the ability to search on the input term instead of the corrected search, at least for now.

As mocks have to be updated due to the addition of the Content-Type header, the test will always fail, even in MockOnly mode, due to the reasons mentioned above, so it should be removed.
