Preserve active filters in Edit/Delete return URL

Change return_url from request.path to request.get_full_path() so that
query params (search, type filter, sort, page) are included. After
saving an edit or confirming a deletion the user is returned to the tab
with the same filters active.

+  `?per_page=`, `?page=`) are retained in the return URL so the user lands back on the same
