Issue #179 Add tests for empty eyaml values

[pillarsdotnet]

This PR only contains test changes for #179 and the tests should fail.

Unfortunately, when I run cucumber as directed, I get the following error:

cannot load such file -- aruba/config (LoadError)

I made the following change:

diff --git a/features/support/env.rb b/features/support/env.rb
index 1b3bfc9..5bb9b85 100644
--- a/features/support/env.rb
+++ b/features/support/env.rb

 require 'rubygems'
-require 'aruba/config'
+require 'aruba/configuration'
 require 'aruba/cucumber'
 require 'fileutils'
 require 'pathname'

Then I ran cucumber again and got a new error:

undefined method `before_cmd' for #<Aruba::Configuration:0x00007fffb9053a00>
Did you mean?  before (NoMethodError)
   /home/rvincentii001/github/hiera-eyaml/features/support/env.rb:29:in `block in <top (required)>'

I made an additional change:

     ENV['HOME'] = Pathname.new(ENV['SANDBOX_HOME']).realpath.to_s

And this time the tests did run, but I got lots of unexpected No such file or directory errors.

I had to close and reopen the PR to trigger github actions

Tests should have failed. They passed, so either the added tests are inadequate, or the reported bug does not actually exist.
