Remove registration for collection-specific events in Context.cs

[Christian Oeing]

In the Value setter of Context.DataNode Collection-specific events are registered for to invoke the ValueChanged event even if the items of the bound collection changed. But the DataBinding won't forward the event anyway, so the events are obsolete.

Removed registration for collection events in DataContextNode

Reverted the change as it is not needed for the DataBindings, but for the child nodes, so something like "MyCollection.3" is possible as a path to get the 4th element of a collection.
