[IMP] core: remove prefetch on Module during loading

If upgrading a database across an addition of a new field to
ir.module.module (which is uncommon but does happen), the field
prefetching would try to load the field before the database schema had
been upgraded, leading to a loading error.

Since we *only* want / need the module's name, we can `search_fetch`
to preload just the field we need, and avoid ancillary
prefetching. It's a bit of an unnecessary optimisation compared to
just turning prefetching off, but it's also simpler (shorter) here
so...
