Add #remove on JsxElement and JsxSelfClosingElement

[dherault]

Add support for JsxElement.remove and JsxSelfClosingElement.remove

If anything just ask I'm around.

Thanks, but it's not so simple unfortunately. Once spaces are added then it gets much more complicated because spaces have meaning in JSX. It's why I haven't had the time to add this functionality yet. For example:

it("should remove the JsxElement child when has spaces", () => {
      doTestWithJsxElementChild(
        `var t = (<jsx>
        <jsx2></jsx2>
      </jsx>);`,
        `var t = (<jsx></jsx>);`,
      );
    });
