notifications,presence-status: check if interfaceConfig is declared 

Protectt ourselves against interfaceConfig being undeclared. typeof
interfaceConfig will return "undefined", but that's different than having some
window.interfaceConfig = undefined, even though the valus is the same. The
former will give a ReferenceError.
