Can't execute DELETE without body.
I'm trying to create Request just as:

```
Request.Builder builder = new Request.Builder().url("URL");
builder.method("DELETE", null);
```

(because there are no `.delete()` method)

When I'm trying to execute such request it crashes, with error message:
`java.lang.IllegalStateException: Cannot stream a request body without chunked encoding or a known content length!`

As I get it, it happens because DELETE can "has request body" (`hasRequestBody` returns `true` for DELETE) and when we are trying to create request body it blows up, because neither `contentLength` info provided nor `Transfer-Encoding` is set to `chunked` because no body provided.

So, there is workaround: just add `Content-Length: 0` header.

Looks like it is somekind related to #605.
