[Tracking Requested - why for this release]:

Partial backout of the incorrect merge conflict resolution.
8eef5d2cc850 in Bug 1300654 incorrectly resolved a merge conflict and backed
out part of the fix for Bug 1280829. Relanding.

Fixup bad merge conflict resolution from Bug 1300654/8eef5d2cc850

Approval Request Comment
[Feature/regressing bug #]: The build was broken on Aurora with the landing of bug 1299694. The fix for that is in bug 1300654, however that had a mismerge, so we also need this patch to fix the mismerge.
[User impact if declined]: Some videos which setup EME but don't actually use EME will not play.
[Describe test coverage new/current, TreeHerder]: We have a specific test to test this case, it's currently on aurroa.
[Risks and why]: Low, fixing a bad merge.
[String/UUID change made/needed]: None.
