stream: update emit readable debug statement
Currently, the debug statement in emitReadable is emit readable
which
can be interpreted as the readable event is going to be emitted. But
I think the intent of this debug statment is just that the
emitReadable_ function was entered. If that was not the intent then
perhaps the debug statment should be moved into the if statement below
it.
