Separate ads rendering and AdsManager init

Browse Source 
In a later change it will be necessary to be able to destroy the ads
manager if all ads are skipped while creating ads rendering settings.
This change prepares for doing that by not having the ads manager
passed into the method (so the caller can null or initialize it).
