Fix Active Directory reconcilor delegate's creation

Active Directory's account reconcilor currently gets instantiated for
all Active Directory enrolled devices for which Chrome OS Account
Manager has been turned on. But we have a pending bug
(https://crbug.com/1008349) which makes the usage of Chrome OS Account
Manager on Active Directory devices a bit buggy.

Fix the initialization condition to check whether Chrome OS Account
Manager is available for the session, instead of checking for the flag.
