fish: erased functions still get autoloaded

[rsteube]

completions need to be invoked once before they can be replaced so that they are not autoloaded:

complete --do-complete 'chown ' > /dev/null
complete --erase -c 'chown'
complete -c 'chown' -f -a '(_carapace_lazy chown)'

needs: fish-shell/fish-shell#6716

[rsteube]

workaround:

touch ~/.config/fish/completions/chown.fish

[dwt]

Looking at the linked fish issue fish-shell/fish-shell#6716 it seems to me the underlying issue may have been solved. So perhaps we can get rid of the ugly hack in the fish config:

mkdir -p ~/.config/fish/completions
carapace --list | awk '{print $1}' | xargs -I{} touch ~/.config/fish/completions/{}.fish # disable auto-loaded completions (#185)

As it greatly slows down shell startup.

Note that this fix exists only in the upcoming 4.0 release.
