A renaming script evaluating to an empty name would cause files to be renamed to e.g. "_mp3", breaking the file extension. Now the original filename will be kept.

- access times are likely to differ, a race condition is possible
- stat() has be done after the change to be able to compare
- comments added
- force sync after modifying test file
- make code easier to understand

Since Python 3.3, ns parameter is available
"The best way to preserve exact times is to use the st_atime_ns and st_mtime_ns
fields from the os.stat() result object with the ns parameter to utime."
Make time preservation testable.
