[PATCH] test: fix compact backup / restore test

[David Bremner <david@tethera.net>]

It was looking in completely the wrong place for the backup and the
(test) xapian database. Unfortunately test_begin_subtest hides the
relevant errors.

I found this bug because 

  id:9ee3f2334a117b0a1b88650f44432423cbe95fd7.1383315568.git.jani@nikula.org

did _not_ break any tests. Which was puzzling.
