DevSuite T&C's signing status check doesn't work for users created before May 18th

Customers report issues with using Account Page (#1) in Development Suite Installer, Rick Wagner reported this and found out that users registered before May 18th cannot use login/password to install devsuite, because download manager returns 'false' for T&C's signing check. Workaround for this cases is to go again through registration process and use new registration credentials.

For users created before April release it just returns the message: "Invalid user credentials for user <user.name>".

UPDATE:
Workaround is to try to sign in into developers.redhat.com account, accept T&C's requested at sign in time, proceed to Container Development Kit Download and download CDK itself not Development Suite Installer. This will trigger request for any missing info including T&C's signing.
