Handle expired refresh tokens by reloading the page

If a user's refresh token expires when their access token is also
expired, they cannot obtain a new access token without authenticating
with the openid provider.

Currently StoryBoard doesn't handle this situation, and the session
ends up in a state whereby the access token is invalid and most
requests cause errors due to this.

This commit hackily fixes this by reloading the page if the request
for a new access token fails, such as when the refresh token is
expired.
