Change user list to preserve search string & paging

When using the page at `/user/search`, if you go to the second page or use the search term, and then go back, the paging and search filters is not preserved. You are back to page one, without a search string.

Ideally this page should preserve everything when you go back:
- paging
- Whether All, Active, or Inactive is preserved
- The value of the search box
- Scroll position

However, recognizing that the scroll position can be challenging to implement, if we could just get the paging, filters and search string preserved that would be a huge win, and we can make a separate issue to resolve the scroll position.
