Bug 10230: no need to use SimpleSearch for matching auths

When introducing QueryParser, I introduced a check for QueryParser at
too high a level, causing authority matching to try and use SimpleSearch
for authorities prematurely, when SearchAuthorities should be handling
it. This patch corrects the level of the check. This patch only moves
three lines, but thanks to the change in if level, it adjusts the
indentation quite a bit.
