[PATCH] search: avoid repeated mbox results from search

[Eric Wong <e@80x24.org>]

Previous search queries already set sort order on the Enquire
object, altering the ordering of results and was causing
messages to be redundantly downloaded via POST /$INBOX/?q=$QUERY&x=m

So stop caching the Search::Xapian::Enquire object since it
wasn't providing any measurable performance improvement.
