[Fix] nvm uninstall: fix alias cleanup glob expansion

The `*` glob was inside double quotes, preventing shell expansion. `nvm_grep -l` received a literal `*` filename instead of the list of alias files, so aliases pointing to uninstalled versions were never cleaned up.

Bug introduced in 7807a9f09e.
