abbr: Erase the old universal variable with abbr --erase

Browse Source 
This means cleaning out old universal variables is now just:

```fish
abbr --erase (abbr --list)
```

which makes upgrading much easier.

Note that this erases the currently defined variable and/or any
universal. It doesn't stop at the former because that makes it *easy*
to remove the universals (no running `abbr --erase` twice), and it
doesn't care about globals because, well, they would be gone on
restart anyway.

Fixes #9468.
