Suite `testRestrictUriReUseSlug` fails if the server DOES NOT create second resource

[no-reply]

The test is intended to cover the requirement that LDP servers that allow member creation via POST SHOULD NOT re-use URIs., but fails if the server does not respond 201 Created when requesting a resource with a duplicate Slug.

See:

ldp-testsuite/src/main/java/org/w3/ldp/testsuite/test/CommonContainerTest.java

Lines 907 to 927 in 816e98a

	private void testRestrictUriReUse(String slug) throws URISyntaxException {
	skipIfMethodNotAllowed(HttpMethod.POST);
	// POST two resources with the same Slug header and content to make sure
	// they have different URIs.
	Model content = postContent();
	String loc1 = post(content, slug);
	// TODO: Test if DELETE is supported before trying to delete the
	// resource.
	// Delete the resource to make sure the server doesn't reuse the URI
	// below.
	buildBaseRequestSpecification().expect().statusCode(isSuccessful()).when().delete(loc1);
	String loc2 = post(content, slug);
	try {
	assertNotEquals(loc1, loc2, "Server reused URIs for POSTed resources.");
	} finally {
	buildBaseRequestSpecification().delete(loc2);
	}
	}

The test as written wants to check that the newly created resource has a different URI than the one requested. As far as I can tell, it should also be acceptable to refuse to create the resource. We respond 409 Conflict, which seems to offer greater predictability to clients.
