Issue:
recursive copy does not copy files, only directories
<!---
Verify first that your issue/request is not already reported on GitHub.
Also test if the latest release, and master branch are affected too.
-->

##### ISSUE TYPE
<!--- Pick one below and delete the rest -->
 - Bug Report

##### COMPONENT NAME
copy

##### ANSIBLE VERSION
<!--- Paste verbatim output from "ansible --version" between quotes below -->
```
ansible 2.4.2.0
  config file = /etc/ansible/ansible.cfg
  configured module search path = [u'/home/user/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/dist-packages/ansible
  executable location = /usr/bin/ansible
  python version = 2.7.14+ (default, Dec  5 2017, 15:17:02) [GCC 7.2.0]

```

##### CONFIGURATION
<!---
If using Ansible 2.4 or above, paste the results of "ansible-config dump --only-changed"
Otherwise, mention any settings you have changed/added/removed in ansible.cfg
(or using the ANSIBLE_* environment variables).
-->
default configuration

##### OS / ENVIRONMENT
<!---
Mention the OS you are running Ansible from, and the OS you are
managing, or say "N/A" for anything that is not platform-specific.
Also mention the specific version of what you are trying to control,
e.g. if this is a network bug the version of firmware on the network device.
-->
Linux / Linux

##### SUMMARY
<!--- Explain the problem briefly -->
The copy module copies only directories, no files. The directories look fine and are created recursively, however no files are copied. If you run the playbook again then the files too are copied.

##### STEPS TO REPRODUCE
<!---
For bugs, show exactly how to reproduce the problem, using a minimal test-case.
For new features, show how the feature would be used.

I am able to duplicate this.  On the first pass only the directories are created.

```
mkdir -p source/{one,two}
touch source/one/afile
```

I checked the 2.3 behavior, and 2.3 requires that all the directories be pre-created, so it looks like 2.4 took a step forward, but it's not complete.
I think I've found the bug (really, several bugs).  I have a workaround for you until I get a real fix applied.  This only happens with relative paths for the target directory.  If you use an absolute path, it should work fine.
I reproduced this bug.

When I tried on python version 3.6, THe only directory are created.

But, python version 2.7.10. The file are created.

This is my playbook, source directory listing and version of ansible
