vcl: fix crash in Window::LeaveWait()
Crashreport signature:
SIG Fatal signal received: SIGSEGV code: 128 for address: 0x0
program/libmergedlo.so
vcl::Window::LeaveWait()
vcl/source/window/mouse.cxx:640
program/../program/libsclo.so
ScSpellingEngine::ShowTableWrapDialog()
sc/source/ui/view/spelleng.cxx:315
program/libsclo.so
ScConversionEngineBase::FindNextConversionCell()
sc/source/ui/view/spelleng.cxx:168
program/../program/libsclo.so
ScSpellDialogChildWindow::GetNextWrongSentence(bool)
/opt/rh/devtoolset-10/root/usr/include/c++/10/bits/unique_ptr.h:173
Seeing that e.g. Window::GetDropTarget() also handles a disposed
vcl::Window, let's do the same here.
