TestRunReturnsStartError expected a start with no TLS flags to fail;
since the first-install wizard that start succeeds (install mode with
a self-signed certificate) and Run blocked until the 10 min timeout.
Use --tls-cert without --tls-key, which is always refused.
TestICMPStateMachine could advance the fake clock twice in one step on
a slow runner, firing an extra probe ([1 1 1 0 0 1 1]). Advance once,
only after the ICMP loop has re-armed its timer.
