Fix BrowserTest.WindowsSessionEnd by moving a virtual call
from the constructor to the Init() function().

The virtual call in the constructor of the base class doesn't
get dispatched to the child class since we haven't started to
construct it yet.  Instead, defer the call until after we've
finished creating the object.
