Sender doesn't advertise file transfer proxy
Bug description
In the current repository version the streamhosts-list is missing the avaliable proxies.
Proxy adress is in 'file_transfer_proxies' and 'use_ft_proxies' is active.
This worked in gajim-15.3 so this is a regression.
Steps to reproduce
- Use gajim-hg
- Disable port forwarding so a proxy is needed
- Send file - will fail
Software versions
OS version: Arch Linux
