tdf#166837 vcl: Unset terminate listener once it's been notified
When the TransferHelper's TerminateListener gets notified
that the desktop terminates, i.e. when
TransferableHelper::TerminateListener::notifyTermination
gets called, clear TransferableHelper::mxTerminateListener
once it has done its job (flushing content to the clipboard).
This prevents the TransferableHelper dtor from later trying
to create a Desktop instance using Desktop::create (to
remove the listener), which throws an exception because the
desktop has already been terminated, as seen with the qt6 vcl
plugin for the tdf#166837 scenario.
