What does this PR do?

Adjusts x-ray/dd-trace parenting rules, so that when merging is turned on and a dd-trace context is in the incomming message, the dd-trace trace-id is used, and the x-ray parent-id is used.

Motivation

Fixes the flamegraph, so we can have dd-trace -> x-ray(eg apigateway) -> dd-trace parenting relationships.

Testing Guidelines

I've added a unit test, and tested this manually. Integration tests weren't useful because we mask trace-ids.
