search: reinstate "uid:" internal search prefix

User-supplied queries (via PublicInbox::IMAPsearchqp) may
restrict messages to certain UID ranges in addition to the
limits we impose ourselves for mailbox slices.  So we'll
continue to ask Xapian::QueryParser to "uid:" numeric ranges.

Fixes: 4b551c884a648b45 ("imap: support isearch and reduce Xapian queries")
