@Tony, great catch! I have tested your changes and reproduced the bug.
Now list-contexts does not show any active context when ccmni0 is down.

However, NM is not able to recover from this situation. It tries to add
routes before we get the UNSOL_DATA_CALL_LIST_CHANGED event in ofono.
After that it tries to activate a context, but fails. I think that for
some reason it cannot completely recover after the error adding routes.
I also see that I get the bug always and that there is a suspicious line
from a kernel driver saying "CCMNI0 close" that I do not know who is
triggering. I have tried also with NM from silo 9, but no luck either.

Please see attached log. To me these lines are interesting:

So we are near, but more changes are needed.

Title:
  Leaving Wifi does not connect to mobile carrier data (GSM)

Status in the base for Ubuntu mobile products:
  Confirmed
Status in ofono package in Ubuntu:
  In Progress
Status in ofono package in Ubuntu RTM:
  In Progress

Bug description:
  After leaving my home or work wifi, my Bq phone cannot connect to the
  data from my mobile carrier. The only thing that works is rebooting
  the phone.

  Steps to reproduce:

  1- Connect your phone to password secure Wifi.
  2- Suspend phone.
  3- Leave wifi area and resume phone
  4- Wait for 3g data to kick in (appears 3g indicator instead of wifi)
  5- No connection established. I have waited for more than 30 mins.

  6- A reboot of the phone fixes this issue.

  Really annoying to have to reboot phone 3-4 times a day.
