Stop performing the asset save part of baked texture uploading on the UploadBakedTexture cap asynchronously. 

This prevents a possible race condition where the client would be told all baked textures had updated before they were in the asset service.
The client would then trigger a set appearance which, after a delay, would send the avatar appearance out to other clients.
The race condition seems unlikely because of this delay but it's still possible.
Might help with grey avatar appearances.
