Extension relays on "Keep me signed in" being checked #43

If someone logs in when "Keep me signed in" is off, WhatsApp will not save WASecretBundle in its local storage, and a result, the extension will not work.

crypto.js:24 WhatsAppInvisible: can't decrypt packet due to exception:

Fixing this would require using the session storage instead.
