#7089: Unmapped lavfi outputs with unlabelled pads automatically included
--------------------------------+---------------------------------------
Reporter: Gyan | Type: defect

'''Summary of the bug''':
Filtergraph outputs without a labelled pad are automatically included in
the output even with `-map`. If labelled, expected "unconnected output"
error is shown.
'''How to reproduce''':
`ffmpeg -f lavfi -i testsrc -f lavfi -i testsrc -filter_complex
"[0:v][1:v]psnr[out];[0]null" -map [out] -f null -`
