gps global origin stream - make sure we can always send out the message at least once on request 

When requesting a message from a stream that is not active we start the
stream with interval=0 and call the request method once. For all streams
this works fine except the gps_global_origin. For this one the request method
is actually overidden to throttle down the rate and not just send out the message.
This will cause this message to never being sent on request if the stream
is not active by default.
