Fix CDN downloads not always calling GetCdnConfigRequest (#222)

Browse Source 
On previous tests, Telegram didn't return information about CDNs
on the initial GetConfigRequest. However, it may do so, and it's
necessary to call GetCdnConfigRequest even when a second call to
GetConfigRequest isn't required.
