  Network Manager + OpenVPN does not respond to DNS server change on

Bug description:
  Discovered on Kubuntu 16.10, upgraded from a fresh install of 16.04. While I 
only have the one computer to test with, the 16.10 is definitely relevant (I 
did not have this problem on 16.04)  but I can't tell if the upgrade is part of 
it,  (the upgrade may or may not be relevant).

  Have "full time"  wired or wireless connection  (does not matter which used)
  Part time OpenVPN connection set up via NetworkManager.

  Steps to reproduce
  1. Fresh boot
  2.  ping a device on the VPN network  (eg amachine.remotelan ) Result:  
"ping: amachine.remotelan: Name or service not known"
  3.  Connect to the VPN service via Network Manager.
  4. ping amachine.remotelan  -  result:
   PING amachine.remotelan ( 56(84) bytes of data.
    64 bytes from amachine.remotelan ( icmp_seq=1 ttl=127 
time=7.75 ms
  5.  Disconnect from the VPN service again.
    ping result again "ping: amachine.remotelan: Name or service not known"

  6. Reconnect to the VPN again, and ping again

     "ping: amachine.remotelan: Name or service not known"

    However "ping"  responds successfully as expected

      PING ... 192.168.... 64 bytes from .. etc   to the ping by name

  Further info I'm going to add in a subsequent comment. (just annotating 
syslog right now!)
