`cargo sqlx prepare` removes a Windows only query cache

When updating the sqlx query cache for CI we usually just run `cargo sqlx prepare -- --all-targets --all-features --tests`.
This should in theory find all the queries for all platforms but for whatever reason it removes cache for a query in `Location::all()` method, which is Windows-only.

As a workaround one can explicitly target the Windows platform, but this in turn removes some other unrelated non-Windows queries, so some manual intervention is required.
