Some devtools tests had been forced to run in e10s with just 1 content process in bug 1301340 and bug 1303113 because they were failing. Now there seems to have been enough e10s messaging fixes that these tests work again. It seems safe to re-enable multi-content-processes for them now. MozReview-Commit-ID: ENfDdIXvIAI
