    Fix sync point delete

    When a resource failed, the stack state was set to FAILED and current
    traversal was set to emoty string. The actual traversal was lost and
    there was no way to delete the sync points belonging to the actual
    traversal.

    This change keeps the current traversal when you do a state set, so that
    later you can delete the sync points belonging to it. Also, the current
    traversal is set to empty when the stack has failed and there is no need
    to rollback.

    Closes-Bug: #1618155
