CppTools: Use editor manager's codec as fallback

...for reading not already opened files.

This partly reverts commit f7c68f6. In case TextFileFormat::detect()
fails, the user configurable editor manager's codec is used instead of
QTextCodec::codecForLocale().

Adds also a qWarning() to easier detect encoding errors.

Task-number: QTCREATORBUG-10378
