devise_token_auth: A few refreshes after login gives me a blank access token and expiry, logging me out

When posting issues, please include the following information to speed up the troubleshooting process:

• Version: which version of this gem (and ng-token-auth, jToker or Angular2-Token if applicable) are you using?

Using redux-token-auth which autorefreshes the token on validateCredentials. Seems to mostly work fine until an invalid response.

• Request and response headers: these can be found in the “Network” tab of your browser’s web inspector.
