Merged in [18858] from kivinen@iki.fi:

Remove the automatic redirect from latest version to page without version number (also from tests), and made sure when viewing old snapshot which also happens to be last revision for draft where we have rfc, we show information from the draft, not from the rfc. Fixes issue #3162.
