Fixed incorrect display on group members

Group account name is displayed, instead of
members list, caused by loader ids of group
metadata and group members set to zero.

Fixed to set loader id of group metadata to
none zero.

Test: Click the emergency call button in lock
screen after device booted, then enter ICE group
or any group/label. The group ui will display
group account name.
