LP173259 - Array error appears in search box while placing hold after advanced search

The place-hold code assumed it was not in "_adv" parameter mode.  This
assumption was faulty.  Now, the link generated for Place Hold will
translate the argument list to the single-line format that Place Hold
expected, when necessary.

Testing procedure:

Set holds for all the following items, observing that the searchbox in
the searchbar is not blank and does not contain ARRAY(xxx).

Basic Search / Place Hold
Basic Search / Record Detail / Place Hold
Advanced Search with a plain search term / Place Hold
Advanced Search with a plain search term / Record Detail / Place Hold
Advanced Search with a fancy (multiline) search term / Place Hold
Advanced Search with a fancy (multiline) search term / Record Detail / Place Hold
