`nvm_ls` decides whether a version dir is worth searching with `ls -1qA`, which
also counts dotfiles, but then collects versions with `find "${DIR}"/*`, which
never matches them. A dir holding nothing but hidden entries passes the guard,
so when `nullglob` is not set `find` is handed the literal `*` and `nvm ls`
prints "No such file or directory" to stderr.
Drop `-A` from the guard so both halves agree on what counts as an entry.
Fixes#3727.
