[PATCH] v2writable: compatibility with SWIG Xapian binding

[PATCH] v2writable: compatibility with SWIG Xapian binding

[Eric Wong]

The SWIG binding won't auto-convert IV/UV to PV like the XS
Search::Xapian binding would, so workaround that shortcoming
for now.

Fixes: a367ec1b15a2458 ("mbox: disable "&t" on existing Xapian until full reindex")
