With the refresh token code added to UserCloudPolicyManagerChromeOS,
has_auth_cookies() check is no longer necessary since
UserCloudPolicyManagerChromeOS::FetchPolicyOAuthToken is smart to handle both
auth cookie and refresh token cases.

That is, this line (and the TODO at line 152 :) can be deleted now.

Done.
