[FIX / Improve] #17456 when tag script included atribute src, intellisense suggest JS code, but don't end tag "</script>"

[ghost]

• VSCode Version: 1.11.1
• OS Version: ALL

Steps to Reproduce:

#17456

This is documented as requiring an end tag: https://developer.mozilla.org/en/docs/Web/HTML/Element/script

This is unlike br, which is documented as not having an end tag: https://developer.mozilla.org/en/docs/Web/HTML/Element/br

[ghost]

intellisense suggest and to complete (when I write < and press tab) end tag like

<$ (this tag doesn't exist in HTML file)

instead of </script>

when tag <script> include attribute src, better is when intellisense to suggest </script>

(sry for my English)
