Get rid of delayed runnable and change visibility instead for ContentViewRenderView

A better fix to not missing any callbacks during Java initialization is setting
the SurfaceView visibility to VISIBLE only after libraries has loaded. This
change removes the delayedRunnable setup and adds an assert to make sure we dont
have a valid surface before native load.
