placement/objects/resource_provider.py missing test coverage for several methods

[Chris Dent]

In the extracted placement, the coverage tests run both unit and functional tests. This is because so much of the functionality is tested by gabbi. In those runs we can see that a few methods in placement/objects/resource_provider.py are not reached. They are:

Fixed in https://review.openstack.org/#/c/624460/ . Not sure why the association didn't happen.
