All paths in RTSP sends fallbacks correctly when there's no source but not HLS.

Describe how to replicate the issue

RTMP also doesn't work. I have the following config:

paths:
  logo:
    runOnInit: ffmpeg -re -loop 1 -framerate 25 -i /logo_320.png -c:v libx264 -pix_fmt yuv420p -vf scale=320:240 -f rtsp rtsp://localhost:$RTSP_PORT/$RTSP_PATH
  wolfman:
    source: publisher
    fallback: /logo

I can connect to /logo and it works fine but if I try to connect to wolfman, no matter if rtsp, rtmp or hls I get nothing. Example log entries:

2023/04/24 06:52:46 INF [RTMP] [conn 192.168.10.1:48030] opened
2023/04/24 06:52:46 INF [RTMP] [conn 192.168.10.1:48030] closed (no one is publishing to path 'wolfman')

Same here. Fallback does not start at all:

rtsp: no
webrtc: no
srt: no

rtmp: yes
rtmpAddress: :1935
rtmpEncryption: "no"

hls: yes
hlsAddress: :8080
hlsAlwaysRemux: yes
hlsVariant: mpegts
hlsSegmentCount: 10
hlsSegmentDuration: 1s
hlsPartDuration: 200ms
hlsSegmentMaxSize: 50M

paths:
  nostream:
    runOnInit: ffmpeg -re -stream_loop -1 -i ./nostream.flv -c copy -f flv rtmp://localhost:1935/nostream
    runOnInitRestart: yes

  "~^demo/":
    source: publisher
    sourceOnDemand: no
    sourceOnDemandStartTimeout: 10s
    sourceOnDemandCloseAfter: 10s
    overridePublisher: yes
    fallback: /nostream

Fallback doesn't work on HLS #1007
