Brush up the text edit example

- Use initializer lists
- Use u instead of QLatin1String()
- Fix some clang warnings about else after return, constFirst()
- Streamline code
- Remove slot TextEdit::printPreview() which is not needed
- Rename variable fileName to pdfFileName in filePrintPdf()
  to disambiguate from this->fileName

Pick-to: 6.1
