The FAVORITES-mode empty state ("nothing starred yet") shared its
MessageState call with the ALL-mode empty state ("account has zero
repositories"), inheriting a hardcoded 로그아웃 action that only made sense
for the latter. Gives FAVORITES-mode its own action: "전체 저장소 보기",
wired to the same onShowAllRepositories the tab row already uses.
Live bug report: "현재 화면 즐겨찾기가 안되어있는데 로그아웃할거냐는
버튼이 왜 있지?" Live-verified the fix on-device.
