http tests should cover the client originated trace use case

[codefromthecrypt]

@thegryfon noticed that in community axios implementations, some leak contexts and you wouldn't necessarily know until a second root trace is attempted.

here's an example scenario I think tests could cover:

there is no parent trace in scope create a client request create a second client request verify that both client requests are root spans
