routers/user: ensure that decryption of cookie actually suceeds (#7363)

Browse Source 
Previously, only the first return value of ctx.GetSuperSecureCookie
was used to check whether decryption of the auth cookie succeeded.
ctx.GetSuperSecureCookie also returns a second value, a boolean,
indicating success or not. That value should be checked first to
be on the safe side and not rely on internal logic of the encryption
and decryption blackbox.
