Jingle File Transfer doesn't work without Farstream library
Bug description
Jingle File Transfers don't work if Farstream library is not installed. But the implementation of Jingle File Transfers doesn't depend on Farstream.
Steps to reproduce
Install Gajim without Farstream and try to do a file transfer, only SI file transfer is possible. [https://trac.gajim.org/wiki/JingleFileTransfer]
Software versions
