Don't show rewards pane if api account is not found

[irisli]

If a user creates an account using one fbgive api and then tries to log in with with the client pointed to another fbgive api, fbgive responds with {"status":"fail","message":"This update token is invalid.","code":"invalid_update_token"}.

When this happens the client shows a messed up reward pane. The reward pane should not show at all.

I disagree we should hide the reward panel in this scenario. Having a subtle failure behavior in this case is not desireable.

Instead, we should squawk loudly at you. "Error: your user information could not be retrieved" should show up as a flash message, or something similar.

This will only ever occur when a developer is toggling back and forth between environments, or has a misconfigured config.js, and so we should fail fast and hard so they know there is a problem to resolve.
