fix(messenger): send friend look for offline friends in friend list

FriendsComposer only serialized a buddy's look when online, sending an
empty string for offline friends. The look is already loaded from the DB
for every friend in Messenger.loadFriends (SELECT users.look), so the
gate just discarded valid data: offline friends rendered with the
anonymous/standard avatar in the friend list and messenger, while their
profile (fetched separately) showed the real figure.

Always serialize row.getLook(). StaffChatBuddy keeps a non-null look
("ADM") so there is no NPE risk, and UpdateFriendComposer already sent
the look unconditionally, so this only aligns the initial friend list.
