           Summary: DataView is returning a wrong Count value with a
                    AddNew()/DataRowView.EndEdit () cycle

Test case

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; es-ES; rv:1.9.0.10)
Gecko/2009042700 SUSE/3.0.10-1.1.1 Firefox/3.0.10

It's possible to add a row to a view, and then discard it or accept that row,
using DataView.AddNew () and then DataRowView.EndEdit () on the new added row. 

When DataView.AddNew () is called, the data view is firing a ListChanged event,
and calling DataRowView.EndInit () is firing the same event with the same
members (ListChangedTypew to ItemAdded, NewIndex to the position of the new
row), which is fine.

But in the second time the event is fired (when DataRowView.EndInit is called),
the DataView.Count value reported is wrong - specifically Count+1. But this
invalid value is happening only during the time of the event, since posterior
checks return the right value.

The attached sample prints in .net: (the same Count)

ListChanged = ItemAdded, New Index = 1, Old = -1, Count = 2
ListChanged = ItemAdded, New Index = 1, Old = -1, Count = 2

In Mono we get: (the value in the second time is wrong)

ListChanged = ItemAdded, New Index = 1, Old = -1, Count = 2
ListChanged = ItemAdded, New Index = 1, Old = -1, Count = 3



Reproducible: Always
