Closing a PR on the website does not show it as closed on the list

[shana]

I closed a PR on the website so I could create a new PR from the extension for the same branch. The new one shows up, but so does the old one, both in the "Open" filter. The date on the new PR is updating every time I refresh, so for some reason it seems the status is not updating on the old PR, so the list thinks it's open when it's not.

This also appears to be happening with new PRs being opened on the site. However after a certain amount of time (not sure, about 5 mins?) it updates. Related #407.
