Don't strip Script tag elements

[Archmonger]

Current Situation

The client code currently strips script tags and replaces them with div.

For example, this script element wont appear within the browser's DOM.

@component
def my_component():
   return html.script("console.log('hello_world');")

Proposed Actions

Remove this behavior, since we now officially support script within ReactPy. There's no longer any reason to visually hide the script tag.
