Jerry Aldrich a6f74a33b2 Fix Inspec::Config regression in Inspec::Backend
With the changes in PR #3750, `Inspec::Backend.create` needs to support
both being passed a Hash and being passed an Inspec::Config. This adds
a line to convert a passed Hash to an Inspec::Config.

This also adds unit tests for Inspec::Backend because they were missing.
