Retrieving remote address from listening streams should not throw a warning

### Explanation

In order to verify if given stream resource is an listening socket or accepted connection `stream_socket_get_name($stream, true)` could be used. This behavior is defined by [Zend Engine testcase](https://github.com/php/php-src/blob/master/ext/standard/tests/streams/stream_socket_get_name.phpt).

All HHVM versions despite returning `false` for such call also display warning which, in my opinion, should happened - it forces devs to use silence operator in unit tests.
### HHVM Version

3.6.1 - 3.12.1
### Standalone code, or other way to reproduce the problem

`stream_socket_get_name($streamSocketServer, true)`
Runnable code: https://3v4l.org/jQBGr
### Expected result

`bool(false)`
### Actual result

```
Warning: unable to retrieve peer name [107]: Transport endpoint is not connected in [...] on line [...]

bool(false)
```
