[phonegui-efl-new] Opening contacts without gsm reception doesn't work

[dolf1074]

If you open the contacts manager while you have no gsm reception or you have manually disabled the gsm modem, it crashes.

steps to repro:
1. Open settings manager and push GSM off
2. Open contacts manager

expected result:
- The contacts are shown

actual result:
- contacts manager chashes with the following error:

Failed to handle dbus error: type: <class 'framework.resource.ResourceNotEnabled'>
, 71 (dbus-glib-error-quark), code 32

[dos]

Looks like it's fixed in shr-unstable.
