SERVER-22178 Always retry sorted findAndModify upon write conflict.
Previously, if there was a WriteConflictException while actually doing
the update or delete, we would retry the findAndModify, but if the
update or delete stage detected that the document was already deleted
or that it no longer matched the predicate, it would not retry. This
patch ensures the findAndModify will be retried in either of those
scenarios.
