…sessions. This was coming up in some cert tests, where we commission a device, then factory reset it, then try to commission it again with the same node id. When we went to send CommissioningComplete for the second commissioning, we would try to reuse the existing CASE session (to the pre-reset device), which obviously failed. The fix is to just ensure we have no existing sessions to the relevant node id before we start CASE setup. Also adds a unit test for this case. This caught a bug in the test harness: factoryReset was clearing the KVS of running processes without restarting them, which is not how factory reset would normally work.
