This is a further fix for: https://github.com/ansible/ansible/issues/9092
when the relative path contains a subdirectory. Like:
ansible localhost -m copy -a 'src=/etc/group dest=foo/bar/'
This can be tested with this command :
ansible -c local -m copy -a 'src=/etc/group dest=foo/' all
This is a corner case of the algorithm used to find how we should
copy recursively a folder, and this commit detect it and avoid it.
