The content thumbnailers for each frontend were being provided the contents url. This was only ever used to call the urldb thumbnail setting API. This changes it so the single callsite that passed a valid url adds the bitmap to that url itself in desktop_history.c instead of forcing every frontend to require the urldb API. Additionally the old API could pass the url as NULL which was causing asserts where this was not an expected parameter value. Because of this this fixes bug #2286 which was also present in the monkey frontend as both called nsurl_access() on the url without the NULL check and caused an assertion.
