Fix and simplify get_file_name

Browse source 
This function created a QFile that it didn't need and it returned a
dangling pointer (the std::string object was destroyed at the end of the
function).

The function now returns a pointer that the caller must free. For that
reason, it's easier in copy_image_and_overwrite to just go for the
QFileInfo call.
