Make auto imports optional

Makes it possible to have local composables with the same names as auto-imported ones. Otherwise, auto-imported composables overwrite locale ones.

**/composables/useSupabaseClient.ts**

import { useSupabaseClient } from "nuxt-modules/supabase";

export default () => useSupabaseClient<Database>();
```
