Fix race during shutdown

To avoid a dynamic test case error we need to prevent messages arriving on
unconnected ports. Waiting some time before stopping components ensures that
any messages "in flight" will be delivered to the port before the component
is shutdown and disconnected.

It would be far nicer to mark a testresult "final" and ignore such
errors on shutdown, but I don't think it's possible in TTCN3.

This fixes TC_fc_bvc on my laptop which consistently failed with a DTE
before.
