Description
We didn't implement compact reparenting to the spec. For all retained spans, the parent id should be the entry span.
Our logic was only reparenting to entry span if it was an exit span.
This PR also updates the cross agent tests to exhibit this behavior and cleaned up the
assertParentIdto make more sense if it fails.How to Test
