tdf#143778 these async callbacks expect to have SdrModel::IsChanged of false

when they are entered. They are adapted from the original non-async
SwDrawShell::ExecDrawDlg where the start of SwDrawShell::ExecDrawDlg has...

bool bChanged = pDoc->IsChanged();
pDoc->SetChanged(false);

and the end has

if (pDoc->IsChanged())
GetShell().SetModified();
else
if (bChanged)
pDoc->SetChanged();

and before async dialogs the start and end happened before and after the
dialog appeared and disappeared. The intent seems to be unset the
sdrmodel-changed and restore its original state if the dialogs caused
nothing to happen and to explicitly set SetModified on the document if
something did.

Now the async dialogs callback happens after SwDrawShell::ExecDrawDlg
has ended and so the callbacks start with SdrModel::IsChanged at its
original value (restored by the end of ExecDrawDlg), not the "false"
they were originally written to expect.

For simplicity set the SdrModel IsChanged to false at the start of the
callbacks and continue to restore to the passed in bChanged state
if there was no changes by the callback.
