Add members when creating new group

- Enable adding new members at group creation time
- Modify the existing createNewGroup methods in
ContactSaveService to take an array of raw contact IDs
- Note: adding the contact to the group must be
done with applyBatch instead of a single insert
to the data table because otherwise the raw contact
version will not increase
