If the <references> tag is wrapped (e.g. <div><references></div>) and
the first ref on the page contains a newline, Tidy will get confused and
insert extra paragraph breaks in the output.
We can avoid this easily enough by inserting a newline between
MediaWiki:cite_references_prefix and the first reference's <li>.
Note since this changes the output we also have to adjust the parser
tests to expect the new output.

Apparently the initial space in the class name and the double-escaping
of the JSON were both fixed at some point in the past. I haven't tracked
it down, but the change looks beneficial on the face of it.

This fixes bug 20748 and bug 15819 without breaking the other tests. Reverts r88971.
The conflict with CategoryTree was the old problem of a message being called inside
of a parser callback, this time with clearState for which the hook is global.
