Align eap default sso image name with sso image stream name

I am trying to deploy sso using eap74-beta-sso-s2i.json. But I am hitting problem that value from our template [1] is not same from they image stream [2].
I can workaround by specifying SSO_IMAGE on our side, but isn't it aim to be aligned by default?
