util: Fix two corner-cases in boolean term quoting function
Previously, make_boolean_term did not quote empty boolean terms or
boolean terms that started with '('. These cases are incompatible
with Xapian: empty terms cannot be omitted, and boolean terms that
start with '(' trigger an alternate term quoting syntax.
Fix this by quoting empty terms and terms that contain '('.
