Bug 28196: Insert searchid in URL correctly, so it doesn't follow the hash

Test plan:
1. Search the catalog in the staff client for anything which will return
   at least two results
2. Click on any result to go to the bib detail page
3. Click the edit button for any item attached to the bib
4. Verify that the loaded URL contains &searchid=scs_(a number), and
   that the URL ends with #edititem
5. Make any change to the item, save, verify that your change was made
