Bug 11489: in OPAC search, display "no results" when the only search result is suppressed

If hidelostitems is enabled, and the result of an opac search is a single
lost item, then the OPAC will display a 404 error, rather than a
"no results" screen.

Test Plan:
1) Catalog a record/item such that it is the only result for some search
   e.g. Give it the title 'zxcvb'
2) Enable hidelostitems
3) Mark this item as lost
4) Perform an OPAC search that should result in a redirect to this record
5) Notice you a redirected to a 404 error
6) Apply this patch
7) Repeat step 4
8) Note you new get a "No results found!" page instead

Passes all tests and QA script. Tested:

- Record with 1 lost item, result list = 1
  - Verified without both patches 404 error page is shown
  - Verified with 1st patch, no results page is shown
  - Verified with 2nd patch, the still showing facets are gone
- Record with 1 lost item, result list > 1
  - Record is hidden from result list, but
    - result count is wrong
    - result numbering is wrong
    > This is an old problem, just noting
- Record with 1 lost and 1 available item, result list = 1
  - Detail page is shown, only lost item is hidden
- Record with 1 lost and 1 available item, result list > 1
  - Only available item is shown in result list

Also checked that the lost item shows up with hidelostitems off.
