Props filtered if requested includes can't be resolved

[lachlankrautz]

If includes are requested that are not resolvable by the transformer smokescreen mistakenly filters the props to only those includes that have not been resolved.

eg.
Transformer has available includes "one", "two"

Request is made with include=one,two,three

Smokescreen will return

{
  "one" : {},
  "two": {}
}

One and two are included as normal.
Three doesn't exists and instead is used as filter props.
There is no prop "three" so all top level props are filtered out.
