Test for whether a node can receive webmentions incorrectly checks for whether it should send them

I want to receive webmentions, but not send them.

So on my nodes I have the Send ref-backs box unchecked and the Receive ref-backs checked.

With these settings, however, a webmention from a third party source receives a Invalid target parameter. error in return.

The vinculum_webmention_validate_resource_accepts_webmentions() function, which is checked inside vinculum_webmention_receive() to see whether a node is set to receive webmentions appears to incorrectly check for whether the node should send webmentions:

/**
 * Validate if a resource accepts Webmentions.
 *
 * @param $node
 *
 * @return bool
 */
function vinculum_webmention_validate_resource_accepts_webmentions($node) {
  if (!$node) {
    return FALSE;
  }
  return (bool) $node->vinculum_send;
}

I think this should be changed to:

/**
 * Validate if a resource accepts Webmentions.
 *
 * @param $node
 *
 * @return bool
 */
function vinculum_webmention_validate_resource_accepts_webmentions($node) {
  if (!$node) {
    return FALSE;
  }
  return (bool) $node->vinculum_receive;
}

When I change this I am then able to uncheck the Send ref-backs box for a node and leave the Receive ref-backs box checked and the node is able to properly receive webmentions, but won't (properly) send them.
