Can't send file to an entity which has a JID without resource.
Bug description
I am write a transport which can receive files. But gajim can't send a file: the send button is disabled with hint "To send files you should know a real JID".
Steps to reproduce
- Subscribe a transport which has an SI file transfer feature (I can give you an access to mine if it is needed).
- Try to send it a file.
