`Flac` transcode target is ignored when `skip_existing_formats_check` is `true` and source is `Flac24`

[RogueOneEcho]

I'm working my way through the source and was curious if this behaviour is intentional or not?

If you are attempting to:

• transcode from Flac24
• allowed_transcode_formats contains Flac
• skip_existing_formats_check is false

then I would have expected that Flac would be included in transcode_formats but this is explicitly ignored:

Is this the expected behaviour?
