IIS : iis_site resource not idempotent

puppetlabs-iis 4.0.0
2017.2, 4.10.1
2012R2

Desired Behavior:
The iis_site resource should not be showing up as a corrective change every time Puppet runs if the site has already been created.

Actual Behavior:
The iis_site resource reports a corrective change like so: "ensure changed '' to 'started'"

The sample code that we are using can be found here: https://github.com/puppetlabs-seteam/control-repo/blob/production/site/profile/manifests/app/sample_website/windows.pp#L18

We are also ensuring that the default website gets removed prior to creating our own iis_site: https://github.com/puppetlabs-seteam/control-repo/blob/production/site/profile/manifests/app/webserver/iis.pp#L21
