refresh span name when trace completes in traces list

[codefromthecrypt]

Right now, the trace list has the first span name to complete, not the first span name to start (root trace) in the list. I can't seem to have this refresh to see the much better name.

Example, when the trace is complete, I want to see "user" not "POST" for the last span, or be able to hit '/' and have it fix the list.
