Every one of these seemed to previously use the wrong value for `$interface` -- the interface messages in ProtectionForm and SpecialVersion were being parsed as content language (which is the default for `OutputPage::parseInline`), and the one place where we have actual data in the content language (the user signature, which gets parsed in the content language with the rest of the (talk) page content, see Parser.php::pstPass2) was being parsed as an interface message! Forcing the caller to be very explicit about AsContent() or AsInterface() will help mitigate this in the future, one hopes. Bug: T198214 Change-Id: Ib9d5d8d733a47c967bdf7db3e23fa39f11687063
