This reverts commit 7a8eb0b6.

Without this setting, the newline idempotence of scalar strings changes depending on whether
or not they contain any Jinja2 template blocks.

Add integration tests for fetch/slurp, make powershell fetch/slurp work as close as possible to existing fetch/slurp modules.

Looks like #6881 is also affected by this bug.

Currently when using lineinfile insertafter=EOF for a file that has no newline then the added line is not prefixed with a newline.
As a concrete example, ubuntu distro default /etc/ssh/sshd_config has no newline so lineinfile module cannot be used to add a new line to the end of the file.

Also cleaning up integration tests that had checks for the empty item
attribute in certain results.

Fixes #7535

Fixes #7548

Also adds an integration test to catch this bug in the future.

Fixes #7559

Remove 'python-apt' before testing the 'apt_repository' module.  The
'apt_repository' module has the smarts to auto-install python-apt.  The
integration test will now assert the correct auto-install behavior.

Add integration tests for group_by module. Fixed bug introduced by ansible/ansible#7273 while also fixing issue described in ansible/ansible#6953

* the current state of the ELB was not reflected properly when checking
  the status after a change was made.
* invalid zones caused a traceback when enabling/disabling zones

Also adds an integration test for the above.

Fixes #7254

- reverse the order of new_directory_list returned from split_pre_existing_dir in copy module
