Description of problem: exec restore hooks are failing. Restore is completed successfully although `onError: Fail`` is set, but the expected behavior in which it will execute the command `mysql -u root -e source /var/lib/mysql/world.sql` and then a schema called world should exist is not satisfied.

Version-Release number of selected component (if applicable): 1.1.0

How reproducible: 100%

Steps to Reproduce:

 oc -n mysql-persistent rsh $(oc get pods -n mysql-persistent -o name) mysql -uroot world -e "show tables;" returns `ERROR 1049 (42000): Unknown database 'world'`

Expected results:

database world should appear and the command should not return an error
