remember does not behave as expected

[laszlokorte]

When a finite stream is remembered and subscribed twice it behaves strangely.

import xs from 'xstream';

const userXs = xs.of(1, 2, 3)
  .remember()

userXs.addListener({
  next: (x) =>  bin.log("xs first: " + x),
  error: () => null,
  complete: () => bin.log("xs first: complete")
});
// emits: ---1-2-3-|

userXs.addListener({
  next: (x) => bin.log("xs second: " + x),
  error: () => null,
  complete: () => bin.log("xs second: complete")
});
// emits: ---3-1-2-3-|
// expected: ---1-2-3-|

So the remembered value should reset after completion / when the first subscriber is disposed due to completion.
