Do not log warning if trace update interval header value is empty
What does this MR do?
It prevents logging a normal situation as a warning.
Why was this MR needed?
I saw this warning in the log, but this is a benign situation:
WARNING: Failed to parse "X-GitLab-Trace-Update-Interval" header error=strconv.Atoi: parsing "": invalid syntax header-value= job=737 runner=pYJpZ6jY
