Subject: [PATCH 361/398] sw lok comments: avoid crash an exit after clicking
 the scrollbar

Without this, vcl::Window::ImplTrackTimerHdl() will be called on a
deleted vcl::Window.

Can be reproduced with a comment having a scrollbar in a LOK client,
then clicking on the down button of the scrollbar a number of times ->
crash on exit.

(cherry picked from commit 7c654ee9d51a752e02c0a972de27d699ab5b649a)
