This replaces one of the our larger remaining blocks of code with
explicit logic for message_lists.home with logic that should correct
if we support maintaining a different set of rendered message lists.
This should have identical behavior to the previous implementation
given that all_rendered_message_lists is either just
message_lists.home or that plus the current narrowed message list;
can_apply_locally() is always true for the home message list, and the
list === message_lists.current check is equivalent to the more complex
narrow_state.active() check.
This lets us simplify the long-ish ‘../../static/js’ paths, and will
remove the need for the ‘zrequire’ wrapper.
