Do not rely on internal code.

CookieContainer.cookies was a private member in Mono 3.12:

https://github.com/mono/mono/blob/mono-3.12.1/mcs/class/System/System.Net/CookieContainer.cs#L54

Mono 4.0 -- which Xamarin.Android 5.1 is based on -- has migrated many implementations over to use Microsoft's open-sourced referencedsource repo.

Consequently, the CookieContainer.cookies field no longer exists:

https://github.com/Microsoft/referencesource/blob/master/System/net/System/Net/cookiecontainer.cs
(Look ma! No `cookies` field!)

Instead, the CookieCollection instance is referenced by the CookieContainer.m_domainTable field:

https://github.com/Microsoft/referencesource/blob/master/System/net/System/Net/cookiecontainer.cs#L62
https://github.com/Microsoft/referencesource/blob/master/System/net/System/Net/cookiecontainer.cs#L265

Code is private for a reason. Please avoid using Reflection. If you must use Reflection, please don't complain when your broken code breaks.
