Bug 451138

groups being created with no group name when there is no company name and a user
logs in via user service.

if someone creates a rhn account with no company name, and then logs into the
CSP, we create a group with no company name.

one example in qa:

select * from users where first_name like 'joong%';
select * from group_users where userid = 11197;
select * from groups where gid = 2632;
select * from customer_user_cache where username ='rockoil';
select * from customer_entitlement_cache where user_cache_id = '213';

user has no entitlements. Looking in oracle, they have no company name
(supportable).

thought: if we get a customer w/no company name, we create a company name of
"USERNAME_no_company_name"

See sub task for fixing legacy groups.
