Invite form appears for any node id even when invites are disabled

/node_invite/invite/$nid currently works for every node type and every node.

Nodes are invitable even when:

1. The node's type is not in the list of invitable types
2. When a specific node of an invitable type has set node invite to 'disabled' on the edit tab.

Performing a check for node_invites_enabled in the node_invite_send function seems to prevent this by showing a rather blank page instead:

function node_invite_send($form_state, $node) {
 $node->node_invites_enabled = _ni_node_is_enabled($node);
 if ($node->node_invites_enabled){

   // perform the function as normal
   // The rest of the function sits in here...
   global $user; //etc.

 }
 return $form;
}
