Please try logging out and back in to SynBioHub

[cjmyers]

To fix this, when we get a permission exception and you are logged in, clear the login information to force user to re-login

[Kenzo-Schwab]

If permission exception, give a pop-up message saying that you need to log back in and then clear the log-in information

[Kenzo-Schwab]

also add something for when synbiohub is down
