Crashes if pillar_from_directories is the only pillar configuration

[ipmb]

My provisioner looks like this:

provisioner:
  name: salt_solo
  salt_version: 2016.11
  is_file_root: true
  local_salt_root: .
  state_top_from_file: true
  pillars_from_directories:
    - pillar

When doing the converge, this code block is executed:

kitchen-salt/lib/kitchen-salt/pillars.rb

Lines 32 to 39 in 673b07e

	if pillars.nil? && pillars_from_files.nil?
	if not config[:local_salt_root].nil?
	pillars_location = File.join(config[:local_salt_root], 'pillar')
	sandbox_pillar_path = File.join(sandbox_path, config[:salt_pillar_root])
	cp_r_with_filter(pillars_location, sandbox_pillar_path, config[:salt_copy_filter])
	return
	end
	return

In my case, it failed because my local_salt_root did not have a pillar directory.

If I add:

  pillars:
    fake.sls: []

It works as expected. I would expect everything to work if I only define pillars_from_directories in my provisioner.

Thanks for reporting, I will get this fixed.
