Auto merge of #11636 - szeged:optservicesfix, r=jdm

Fix an incorect behavior, when converting optional services.

As specified in https://webbluetoothcg.github.io/web-bluetooth/#ref-for-blacklisted-2 if any service in the optionalServices are blacklisted, there is no need to throw an error (just remove the service). In this case we don't add the service to the result of conversion.
