If the TC log did not provide list of XIDs to recover, the
commit by XID was skipped during wsrep recovery if binlog emulation
was on. However, with wsrep we want to commit every prepared transaction
with assigned wsrep XID since the transaction has already been
committed in the cluster.

Added a special condition to always proceed to commit by XID in
xarecover_handlerton() if binlog is off and the recovered transaction
has wsrep XID.
