RemoveChildren in Components.js being executed with an undefined component

Hi @artf long time, I hope everything is going good with you and your closed ones.

There's a small case that I wanted to ask what you think before i make a request.

I have a custom link component that is wrapped around a li tag, this link has an event to remove its parent li when is removed.

If i delete the link directly everything works fine, but if I remove an outer parent that contains both li and link components, removeChildren in Components.js gets executed with an undefined component, causing this error to happen

Uncaught TypeError: can't access property "getId", removed is undefined
    removeChildren Components.js:30

This is due to the object being deleted during another callback (the custom one i made) before the removeChildren gets the parameter.

This can be solved by just returning if the removed param is falsey but maybe it's too hackish and i should look for another solution and not make the component delete its parent.

  removeChildren(removed, coll, opts = {}) {
    if (!removed) {
      return;
    }

What do you think?

Thanks!
