Title: JRuby Instrumentation doesn't return X-Trace header

The JRuby instrumentation returns the Java metadata object instead of the actual X-Trace value (`"com.tracelytics.joboe.Metadata@64d813e2"`).

We should update the instrumentation to return the actual X-Trace value and add in tests to validate this going forward.
