Subject: [PATCH] fix(src/core/vdom/patch.js): fix the bug 'root level <script>
 tags will be executed' in issue#11483

Root level <script> tags should not be executed, for consistent behavior. So I remove the code in
<script> tag when the <script> tag is the root element of the template.

fix #11483
