mmcli: don't assume that mm_object_peek_modem or mm_object_get_modem return non null

Browse Source 
This very peculiar case can happen when an intermediate initiliazition step
of a modem fails.

The ModemManager daemon should always expose the modem interface but let not
assume that in mmcli and protect these calls.
