    js: Add missing return values to later_add() handlers
    
    meta_later_add() is modelled after g_idle_add() and friends, and
    the handler's boolean return value determines whether it should
    be scheduled again or removed. There are some places where we omit
    the return value, add them (although the implicit return value of
    "undefined" already gives us the intended result).
