Fix "Re-starting finished log context" spam when creating events (#14947

) `run_in_background` calls re-use the current logging context. When they are not awaited, they can complete after the current logging context has been marked as finished, which leads to log spam. Use `run_as_background_process` instead. Fixes one of the instances of #13090. Signed-off-by: Sean Quah <[email protected]>
