    Remove padding from Fernet tokens

    Fernet tokens were previously percent encoded. This can cause issues with
    clients doing their own encoding or not. By removing the padding and then
    re-establishing it when we validate the token, we don't present that problem to
    clients. This also shortens the length of a Fernet token.
