Web Inspector: Start using Node.prototype.remove

[Nikita Vasilyev]

Convert the following code:

    refElem.parendNode.removeChild(refElem)

to

    refElem.remove()


Note that when refElem.parendNode is null, refElem.remove() is no-op, it doesn't throw any errors.

Is this valid? Isn't "self" here a WebInspector.TreeElement, not a DOM Element?

Yes, although this still works, it works in lucky / poor way.

This is inside of remove(), so it calls remove() again asynchronously, and only stops this loop because eventually the actual RemoveChild DOM event would remove this tree element from the parent. Lets fix this.
