fix: Don't change ConfiguredAddr when adding a transport (#6804)

Before this PR, ConfiguredAddr (which will be used to store the primary
transport) would have been changed when adding a new transport. Doesn't
matter yet because it's not possible yet to have multiple transports.
But I wanted to fix this bug already so that I'm not suprised by it
later.
