The only device where this is a real issue is in arale: after switching
on, then off flight mode:

1. The SIM atom is re-created, as in krillin, but not as in mako.
2. The radio is switched off and then on, but differently from krillin the SIM is not reset.

In mako using flight mode does not show the issue, because the atom is
not re-created. In krillin, the atom is re-created but the SIM is reset
too and it asks for the PIN again, so it is not an issue either. Note,
however, that in all devices restarting from the command line ofono
after having inserted the SIM makes the bug appear.

The consequence of this from the user point of view is that, in arale,
after cycling flight mode, the SIM locked status is not shown properly
in system settings and the user would not be able to disable SIM
locking.

Title:
  SIM is not reported as locked after re-starting ofono

Status in ofono package in Ubuntu:
  Confirmed

Bug description:
  To reproduce this in mako:

  1. Start mako with a locked SIM

  2. Enter PIN

  3. list-modems outpus shows
  [ /ril_0 ]
      [ org.ofono.SimManager ]
          PinRequired = none
          LockedPins = pin

  4. Execute
    # restart ofono

  5. list-modems outpus shows
  [ /ril_0 ]
      [ org.ofono.SimManager ]
          PinRequired = none
          LockedPins =

  which is wrong, as the PIN is enabled, although you do not need to
  enter it at this moment.

  The origin of this is that ofono core sets LockedPins only if it notes
  that we are required to enter the PIN. When the SIM atom is created,
  if at that moment there is no need to insert the PIN it will not set
  the PIN as locked (=enabled).

  For mako this is not a big issue unless it is re-spawned after a
  crash, but in other devices (arale), this happens simply switching
  off, then on flight mode.

  Happens in vivid-proposed image #86.
