FEvaluateActorReferenceChannels don't run on GameThread

When playing back sequences on a character that is bound users will sometimes run into an ensure from FEvaluateActorReferenceChannels.

Steps to Reproduce

I'm just playing one of our Sequences with Bindings for Characters.

It's an ensure : "Playback capabilities aren't meant to be thread-safe. Do not modify or access their container outside of the game thread."
