Keep search result type if searched from result page (#1764)

Whenever OmniSearch was used, the user was redirected to the repository results. However, if you are looking for a different type and want to refine your search after the first results, it makes sense to stay on the same type when searching again.
So whenever a search is started from the search result page the selected type keeps selected.
