updateUser() from GoTrue returns a UserResponse. The UserResponse doesn't contain an error parameter

[JaseElder]

Describe the bug
in updateUser(), updating the user with the same password as current will generate an error: {errorMessage: type 'Null' is not a subtype of type 'UserResponse' in type cast} because in this case it doesn't return a UserResponse

To Reproduce
Steps to reproduce the behavior:

1. call

  final userResponse = await _supabase.auth.updateUser(
        UserAttributes(password: newPassword),
      );

where newPassword == old password.

Expected behavior
I would expect an exception to be thrown, rather than a generic null error.
