fixed empty/no script tag in vue component error

[adamDilger]

This should fix #191 if I've understood what vue-preprocessor.ts does

If there is no script value, just return the code as is

Thank you for your contribution. Could you please use this example and also some variation of it in the snapshot tests?

<template>
	<div>
		<span>hello world
		</span></div>
</template>

<script>
// I am top level comment in this file.
// I am second line of top level comment in this file.
import threeLevelRelativePath from '../../../threeLevelRelativePath';
import sameLevelRelativePath from './sameLevelRelativePath';
import thirdParty from 'third-party';
import React from 'react';
export { random } from './random';
import oneLevelRelativePath from '../oneLevelRelativePath';
import otherthing from '@core/otherthing';
import twoLevelRelativePath from '../../twoLevelRelativePath';
import component from '@ui/hello';
export default {
    title: 'hello',
};
import fourLevelRelativePath from '../../../../fourLevelRelativePath';
import something from '@server/something';
function add(a, b) {
    return a + b;
}
</script>

<style>
div { color: red; }
</style>

These kinds of tests help us to catch unwanted changes through out the code.
Thank 👍

@byara From the looks it seems that there are already a few examples/variations of a standard component in the snapshots, so instead I've added the bug offending scenario (a component with no script tag). Is that all good?

Thanks!
