ve.ui.MWExtensionInspector: Prevent from setting impossible content

Browse source 
XML-like tags in wikitext are not actually XML and don't expect
their contents to be escaped. This means that (usually) it is not
possible for a tag '<foo>…</foo>' to contain the string '</foo>'
(see bug 57429 comment 4 for details).

Prevent the user from doing that by escaping the first angle bracket
'<' to '&lt;' in such inputs when the inspector closes.

Bug: 57429
