Check for existing watched entry in history before sending one

If history entries are added based on user actions (e.g. this does not affect the initial data merge when syncing with Trakt), check the history API if an entry already exists at the watchedAt timestamp to be used. This is only a single API call and is expected to have a small, in most cases probably empty, response so overhead should be minimal. Edit: for movies need to look up the Trakt id first, but that likely happened already as part of loading details from Trakt (e.g. response is cached).
