quick frontends (app): added an "ignore_missing" argument to RemoveListener:
normally an error is logged when removeListener is call on a inexisting listener, but
sometimes listeners are added only in specific scenarios, and it may be handy to try to
delete them without having to explictly check that they have been used.
