[Test Please] Fix for disappearing Pet Par

[Alestane]

So, I've hacked together a little fix for the pet action bar failing to show up. If you have had issues with your pet's action bar failing to appear (especially in spite of other fixes such as ReappearingUnitFrames), please test this out and post feedback, preferably in this Blizzard thread: http://forums.worldofwarcraft.com/th...88170265&sid=1.
