this is absolutely going to cause you pain, get rid of it.

Instead, I think we should probably separate creation of the MojoShellConnection
from binding it to a pipe. You can add a bare create method and call it early in
RendererMain(). That means we can add listeners early.

Then add two bind methods:
BindToMessagePipe
BindToCommandLinePlatformChannel

Done.
