If a stream notification message arives from the daemon side, the event
dispatcher only sets the error state for the stream but does not emit
the stream error event and the corresponding callback is not called.
This patch adds the emision of the event in the cause a stream error
(abortion) happens and the user may act on this using the event
callback.
