Issue
=====
When tracing short-live UST apps in per-pid mode, it happens that traces
are closed before we can send all the streams to the viewer. This can
place the viewer in an uncomfortable position where it is aware of data
streams of a trace but can't get the metadata stream to decode the
events.
Solution
========
Only send the data streams if we have the metadata stream or if the
metadata stream was already sent. This ensures that the viewer will
either have all the {data,metadata} streams or none of them.
