Fix possible pull request broken when leave the page immediately after clicking the update button (#34509) 

If user leaves the page, the context will become cancelled, so that the
update process maybe terminal in an unexpected status. This PR haven't
resolve the problem totally. It uses a background context to not cancel
the update process even if the user leaved the pull request view page.

Fix #31779
