MSC_Tests: Reliably pass TC_cr_before_reset

I was able to reproduce the sporadic cr_before_reset failures by running
both osmo-{stp,msc}-master with --cpus 0.1. In that case the first test
run would fail for me because no BSSMAP RESET ACK was seen. Sleeping
some seconds before sending the messages will make sure all components
are connected.

Note: TC_cr_before_reset is the first test executed in control so this
seems to be why it sometimes fails in jenkins.
