Fix document and vector fixture

[sanders41]

Pull Request

In looking at #962 I noticed that the index_with_documents_and_vectors fixture was not working as expected and therefore the test_vector_search test was not testing what was expected. Because only one document had vectors the document addition task was failing and no documents were added to the index. So test_vector_search was returning no hits because there were no documents in the index. This updates the fixutre to add vectors to all documents, and updates the test to pass with the new results.
