Add tests for recovery deadlock conflicts.

The recovery conflict tests added in 9f8a050f68d surfaced a bug in the
interaction between buffer pin and deadlock recovery conflicts. To make sure
that the bugfix won't break deadlock conflict detection, add a test for that
scenario.

031_recovery_conflict.pl will later be backpatched, with this included.
