[PATCH 4/2] imap: *SEARCH: reinstate "TEXT" search-key

[Eric Wong <e@yhbt.net>]

I accidentally dropped "TEXT" handling while porting
the IMAP search query parser to Parse::RecDescent.
This reinstates it and adds a test to prevent future
regression, and the additional test fixes a counting
error for non-Xapian-enabled systems.
