[main] TorrentInfoEndpoint FFA entries not added to mds

[qstokkink]

The following is commented out:

tribler/src/tribler-core/tribler_core/modules/libtorrent/restapi/torrentinfo_endpoint.py

Lines 112 to 115 in 3343308

	# FIXME: FFA entries
	# Add the torrent to GigaChannel as a free-for-all entry, so others can search it
	# self.session.mds.TorrentMetadata.add_ffa_from_dict(
	# tdef_to_metadata_dict(TorrentDef.load_from_dict(metainfo)))

This seems to have been forgotten and should've been part of #6206, according to this discourse https://github.com/Tribler/tribler/pull/6206/files#r665411356

Also disabled in the test:

	# with db_session:
	#assert metadata_store.TorrentMetadata.select().count() == 2
