Fix bug in PreCommit_CheckForSerializationFailure. A transaction that has
already been marked as PREPARED cannot be killed. Kill the current
transaction instead.
One of the prepared_xacts regression tests actually hits this bug. I
removed the anomaly from the duplicate-gids test so that it fails in the
intended way, and added a new test to check serialization failures with
a prepared transaction.
