[PATCH] test: add regression test for large number of deletions

[David Bremner <david@tethera.net>]

Prior to 9ad19e4454f there was an unhandled Xapian exception when
reindexing after a large number of deletes.  This test was used for
bisection, and will subsequently serve as a regression test.

It turns out my original assessment of the situation was
correct. Whatever the problem was, the delete performance optimization
changes fixed it.
