[Telepathy] [PATCH] fix segfault in got_contact_list_attributes_cb

[Maksim Melnikau]

tp_simple_client_factory_ensure_contact returns NULL for protocols, if
tp_connection_has_immortal_handles=0. Right now its happened for any
telepathy-python based protocols (butterfly, sunsine, mixer).

when tp_simple_client_factory_ensure_contact returns NULL,
tp_simple_client_factory_ensure_contact just segfault in
_tp_contact_set_attributes.

lets assume that contact sometimes NULL here, and skip them
