This prevents an unnecessary SurfaceView from being created. Creating a
SurfaceView is very expensive because this starts multiple threads,
creates the pty, starts the pty process, etc.
Additionally, this was exposing what I believe to be #497 when restoring
state: a surface view was created and destroyed very quickly causing
hangs on some machines. This still needs to be resolved but the behavior
in this commit was still a bug anyways.
