As it was confusing to use the term local file when referring
to a file that was accessible using native APIs and not just
a file that was on a hard disk somewhere already the function
name has been changed.
By renaming it to createNativeFile we keep it consistant with QFileInfo
which has an isNativeFile() function too.
Test also added.
