NM, MM, pppd and systemd logs

I am using NetworkManager 1.8.4 on a linux device without CDC support.

Steps to reproduce:
1. Connect 3G modem
2. Connect to network with NM
3. wait for PPP connection completes
4. kill ModemManager

Actual result:
ModemManager exits correctly, but pppd is still running

Expected result:
pppd exits

Versions:
NetworkManager 1.8.4
ModemManager 1.6.10
pppd 2.4.7
Linux 4.14.29
