A side effect of cd9e50c2c (completions/set: Complete variables of all scopes
when setting, 2024-10-03) is that
HOME=$(mktemp -d) fish
fish_config choose ayu\ Light
set -S fish_color_
gives only completions that have the "Universal variable" description even
though most colors are also defined in the global scope which usually takes
precedence.
Fix this by reordering the completions. (The last-added completion is shown
first which is very surprising, we should change that).
This is not perfect; if the user has already specified `-U`, then we should
probably not show description of the global version. But that's still
worth the trade that this commit makes. Finally, the description could show
something like "Defined in universal and global scope" etc.
