[issue21697] shutil.copytree() handles symbolic directory incorrectly

[Shajunxing]

New submission from Shajunxing:

While using shutil.copytree() and the source containing symbolic directory (not symbolic file), an error will be raised. I checked the source code and found an obvlous mistake: shutil.copytree() using os.path.islink() to checker whether the source is a symbolic link, it's okay, but after doing this, os.path.isdir() should be called because a symbolic link may either be a file or a directry, shutil.copytree() just treated all of them as file, and invoke copy_function to copy it, so error happens.

I don't know whether newer versions have fixed this bug, but I googled it and found nothing.
