OpenTelemetry Bandit: Add a nil check for status

[JohnDoneth]

It appears that WebSockets are reported as having a nil conn.status to the telemetry handler. Due to the conditional in the telemetry handler nil statuses are interpreted as errors (when they are functioning as expected) due to nil >= 500 evaluating to true.

Can you sign the cla?

And is there any way to discern if it's a websocket closing after upgrade? Just so it's clear in tests and comments that this is expected and not open a hole in test coverage.

@bryannaegele I'm still working through with my company on how to proceed with the CLA. I will attempt to adjust the code if possible to see if it's a websocket upgrade once I get word on the CLA.
