Fixes#3176
**Changes**:
- Sets the pagination to page one if the search is updated. This is the norm on most websites, and how users expect it to work.
- Join `setPage` into `updateSearchResults`
- Take a page number in `updateSearchResults`
- Remove unused param to `updateSearchResults`
- Update `watch` to not double requests
- use `scrollToTop` utility function
