Bug 1252650 - Send event response even if GeckoApp is not active; r=me

Enable sending event response when Gecko state is PROFILE_READY. This
happens when Gecko is loaded in the background and GeckoApp is not
active. This is safe because it's only a response to an event from
Gecko, so there is definitely a listener for the response on the Gecko
side already. r=me for a trivial change.
