Fixes the password reset token
It now outputs the raw token & stores the hash
Due to an update in Devise, we must differentiate between the raw token and the hashed token. Only the hash is stored.
Updated test
We no longer "cache" tokens: generate a new one for every request...

Since we can't store the raw value, we can only send an email if we generate a new value (and update the hash)
