MSC_Tests: Extend timeout waiting for Clear Cmd in TC_establish_and_nothing

This should fix the bogus failures we are seeing in this test. The pcap
usually shows that the Clear Command does arrive after about 5 seconds,
but sometimes the internal timer fires before that. Double the timeout
of the test here.
