`findOneAndReplace` should return the document before replacement unless requested otherwise

[skedwards88]

findOneAndReplace defaults to returns the document after the replacement. The other clients default to return the document before the replacement.

Fixed to have the ReturnDocument AFTER by default

void should_replaceOne_document_after() {
        collectionSimple.deleteAll();
        collectionSimple.insertOne(new Document().id(1).append("hello", "world"));
        CollectionUpdateResult u1 = collectionSimple.replaceOne(
                Filters.eq(1), new Document().append("hello", "welt"));
        assertThat(u1.getMatchedCount()).isEqualTo(1);
        assertThat(u1.getModifiedCount()).isEqualTo(1);
        assertThat(u1.getDocument().get("hello")).isEqualTo("welt");
    }
