[IO-386] FileUtils.doCopyFile uses different methods to check the file

sizes.

- The method org.apache.commons.io.FileUtils.copyFile(File, File,
CopyOption...) no longer checks file sizes.
- [IO-443] FileUtils.copyFile methods throw an unnecessary "Failed to
copy full contents from" exception.
- Remove test that does not reflect what happens on disk since we use
Files.copy(Path,Path,CopyOptions)
