[GPRS] NS: Start TEST procedure, not ALIVE procedure, on RESET/RESET_ACK
According to the spec, after an incoming RESET or RESET_ACK, we shall start the TEST procedure, not the ALIVE procedure. Also, when we start the TEST procedure, we have to always send a NS_ALIVE packet at the same time (we didn't in the case of incoming RESET). Furthermore, we now only start TIMER_TNS_ALIVE from within the TIMER_TNS_RESET callback code, where we also make sure that the alive_retries counter is reset to zero.
