Original change's description:
> Code Cleanup: Dedup usages of AccountManager's URL Context
> 
> |InlineLoginHandlerChromeOS| and |ChromeOSOAuth2TokenServiceDelegate|
> use the system URL context because they 'know' that AccountManager is
> going to use the same. This is a leaky abstraction.
> 
> Add a method in AccountManager that returns its URL Request Context.
> This request context happens to be the system URL context for now.
