Invalid use of tr in QQmlJS::Lexer & QQmlJS::Parser

In following files is one big misstake of using tr(). First used argument is context name instead of message text. So Linguist show about ten messages QQmlParser with different developer's comments.

qtbase/src/tools/qdoc/qmlparser/qqmljslexer.cpp
qtbase/src/tools/qdoc/qmlparser/qqmljsparser.cpp

you can find it by common text: "QQmlParser"
