Fix: It possible KeyAlreadyExistException workarounded

It apparently is possible to have 2 Players with Same Steam ID but different Serial ID. Cause unknown.

For both of them the same Identity ID is looked up because that ignores the Serial ID. And therefore I can just replace the value.

Could auso check with if(!containsKey) but since the result will be identical I didn't bother.
