Title: SEC-1900: Fixed by removing dependency to equals method in SimpleGrantedAuthority

Made the role comparision be performed on sets of (role) strings instead of comparing any given implementation of GrantedAuthority with SimpleGrantedAuthority. I.e. the ifAllGranted code is no longer dependent on the implementation of the equals method in SimpleGrantedAuthorization.
