This PR makes ofono signal ordering more sensible:

https://github.com/rilmodem/ofono/pull/129

Although this bug only happens for mako it is not impossible that it
might have appeared for krillin too, as both plugins worked in a similar
way.

For those interested, here is the event sequence that probably makes the
bug appear:

1.- ofono_sim_register() is called. It calls
ofono_modem_add_interface(), which calls g_idle_add() before notifying
of the new interface.

2.- __ofono_sim_recheck_pin() is called. PinRequired is signalled.

3.- Now trigger_interface_update(), the argument to g_idle_add() in
point 1, is called so SimManager interface is signalled.

4.- telepathy-ofono calls GetProps() but, surprise, no properties are
there. This is because the SIM atom has not been notified that there is
a SIM, so sim_get_properties() returns no reply.

5.- Present is finally signalled when ofono_sim_inserted_notify(TRUE) is
called from the *ril/mtk plugin*. This can happen before of after the
sequence described, as there is no coordination with rilmodem SIM
driver. When it happens as described the bug appears.

Title:
  i-network says "Unknown" or "No SIM" on N4 (mako), can't unlock the
  SIM

Status in Network Menu:
  Incomplete
Status in “ofono” package in Ubuntu:
  Triaged

Bug description:
  noticed that i-network is broken on mako. Sometimes after reboot the
  indicator says the modem state is either "Unknown" or "No Sim" even
  though the SIM is present.

  for now the workarounds are:

  If developer mode is not enabled:
   - reboot the phone until you can enter the PIN

  if developer mode is enabled:
  $ adb shell
  $ restart indicator-network

  # system-image-cli -i
