exc_filters: fix deadlock detection for percona xtradb cluster
percona xtradb cluster server produces an error like:
(1213, u'WSREP detected deadlock/conflict and aborted the transaction.
Try restarting the transaction')
which is currently not detected properly and, thus, not retried.
Closes-Bug: #1648818
