Bug 26606: Correctly URI-encode query string in URL loaded after deleting an authority record

If you search for "this & that" and delete one of the results, after
it is deleted the search in the reloaded page is for "this " rather
than for "this & that". The template uses the url filter, which is
for filtering an entire URI where :, &, #, etc. should be left alone,
rather than the uri filter which is for filtering a URI component
where they should be encoded.

To test:
1) Go to Authorities > New authority > New from Z39.50/SRU
2) Search for the Author (corporate) this & that collective
3) Actions > Import, Save
4) From the detail for that authority, Edit > Edit as new (duplicate)
5) Edit the 110 field, add 2 at the end and Save
6) Search authorities for this & that
7) For one of the ones you created, Actions > Delete, confirm
8) The page that reloads should have a search for this & that, not
just for this
