Create Window in OnPreCreate() instead of OnCreate()

OnPreCreate() method is called before OnCreate() always. If the Window
is created in OnPreCreate(), User doesn't have to consider the call
sequence of base.OnCreate() and LoadApplication() methods. Because
the Window will be prepared before OnCreate() is called.
