Stop hardcoding id/ASC for every search

Worst part is that this hardcoding overrides user prefs.
At least now you can use the new global pref from
4.2/configurable-search-order to override.

This does not get us access to user search preferences unfortunately,
because we have to define high up the stack since so much RTIR code
defines defaults and hands off to CollectionList.

It likely wants a default element like ProcessQuery that can be called
from all the various ticket lists that don't just use
Search/Results.html.

Some of this will get cleaner when we no longer have an outdated fork of
the core RT search code in RTIR.
