Fix - codefresh_current_account data source returns 403

[ilia-medvedev-codefresh]

What

Remove unnecessary call to GetUserByID that requires admin token to get the account admins info. Instead infer admin info from /user endpoint which returns the info for all users. As admins are also users the data is there, it is enough to just locate the admins in this existing list.

Why

Closes #131
