core: Fix interpolation tests with nested lists

Browse Source 
Some of the tests for splat syntax were from the pre-list-and-map world,
and effectively flattened the values if interpolating a resource value
which was itself a list.

We now set the expected values correctly so that an interpolation like
`aws_instance.test.*.security_group_ids` now returns a list of lists.

We also fix the implementation to correctly deal with maps.
