Basically we are replacing `null` pointer with `SupportedSigSchemes.DEFAULT` pointer but those values are not being used other than to return with `SSLConfiguration#getSSLParameters()` call. This is unlike `NamedGroup.SupportedGroups.namedGroups` values which are being (needlessly) looked up again and used in `NamedGroup` class. I've created JDK-8370885 to deal with it separately.

Unit test added.
