Update tests that are marked flaky.

QuLogic · QuLogic · commit e05072980ba9 · 2017-06-03T02:23:46.000-04:00
The Mathtext tests should no longer be flaky based on the previous
change.

Mark some PS tests as flaky because they require a lock that sometimes
gets stuck on AppVeyor due to the multiple processes.
