This is another one that's my fault, not yours.  Now that the module supports enabling the puppetdb report processor, and since it should already be enabled by default in PE, and since we actually do want to test that... we should change the setup code to use the module to enable reports and then remove the `reports` key from all of our calls to `with_puppet_running_on`.  I can help with that or even just do it myself as an add-on commit on top of your stuff.
