__fish_complete_subcommand: Just complete -C for a given commandline

Browse Source 
Fixes #10980.

This would, if a commandline was given, still revert to checking
the *real* commandline if it was empty.

Unfortunately, in those cases, it could have found a command and tried
to complete it.

If a commandline is given, that is what needs to be completed.

(note this means this is basically useless in completions that use it
like `sudo` and could just be replaced with `complete -C"$commandline"`)

(cherry picked from commit d5efef1cc5)
