test: Make the connect-stress less likely to bail out due to >32 streams.

When running two connect-stress tests at the same time the liklihood of >32 streams
per sink increases. All it takes is for an event sound to fire to trigger an abort of
the test.

This leaves just a little bit of wriggle room for a couple external streams.
Of course the overall problem is still there but this just makes it
slightly less likely without really affecting the test itself.
