Refactor tst_QFiledialog::completer().

- Streamline code and remove code that has no effect.
- Create temporary directory and files only when it is actually
  required (empty start path).
- Remove try/catch as it is not commonly used in Qt autotests.
  Its original purpose was apparently to ensure temporary file
  cleanup, but that should now work since smart pointers are used
  for temporary files and directories.
- Introduce variable for case sensitivity.
