Error msg on empty response & added search params

- On empty search responses Search page show a error message that there
where no respones.
- For page loads directly to the search page new url query parameters
are checked: adult and media_type. These are then used to fetch updated
tmdb search parameters. Adult = true disables filtering for adult
material and media_type decides if the search is multi, movie, show or
person. (Frontend for filtering media_type is not added yet.)
