Factor out a 'with_duplicate_xapian_job_creation' helper

In a subsequent commit, we will want to wrap an additional section
of code with the addition and removal of a hook that creates a
duplicate xapian job, so it's useful for this to be factored out.

This commit introduces a 'with_duplicate_xapian_job_creation'
method that can be passed a block which will be run with the forced
duplicate xapian job creation.
