This test case checks if the console connection code works in a safe way

Diff to v1:
-- removed semicolons at the end of statements (the C language left some habits :D)
-- added call to usage function (I thought it's called automaticaly. With this this could
be another good function to incorporate in the class and
free the test-writer from re-implementing it again and again)
-- added cleanup function (same comment as above; note: there are some tests that don't have this func.)
the clean flag was added after some testcases.
So... need to update them later.
-- refactored getting of optional parameter "device"
-- added cleanup of stream objects (they'd got cleaned up automaticaly with the disconnect, but
this is safer and enables testing if the stream was in a good state)
