New W3C json-ld-api test structure does not run #262
Description
The JSON-LD 1.1 tests at https://github.com/w3c/json-ld-api/tree/master/tests use manifests with an additional layer of nesting: there's a file called manifest.jsonld that contains a list of manifest files, rather than a list of test objects. This breaks the JsonLdProcessor tests as it tries to process all manifest files and expects the latter structure: a list of test objects.

Solution: either explicitly exclude manifest.jsonld from the processing, or explicitly start with that file to find the "normal" manifest files.
