Subject: [PATCH] fix crash in ThemeService
ThemeSyncableService and ThemeService are owned by each other. On
destruction of ThemeService, ThemeSyncableService gets destructed as
well, but calls RemoveObserver of partly destructed ThemeService object.
To avoid already destructed |observers_| list, move it before
|theme_syncable_service_| definition.
