From: John Harrison <John.C.Harrison@xxxxxxxxx>
The test was updated some engine properties but not restoring them
afterwards. That would leave the system in a non-default state which
could potentially affect subsequent tests. Fix it by using the new
save/restore engine properties helper functions.
