Adam Leff 3ffaee91c2 docker_image resource: properly handle registries in image strings (#2356)
When supplying a docker image that contains a registry with a port number,
such as `localhost:5000/chef/inspec:1.46.3`, the docker_image resource
was unable to locate the image in question due to incorrect parsing
of the repository and tag.
