Use `resolvePackage` instead of `resolveModulePath` in `resolveHasteName`

[kraenhansen]

Summary

This fixes #1128 by calling the resolvePackage instead of resolveModulePath in resolveHasteName. Only resolvePackage has the code to resolve package "exports" and it calls resolveModulePath as a fallback.

Test plan

I've added a failing test which passed as the fix got implemented.

Thanks @kraenhansen - this LGTM (and @huntie), importing to run it through internal CI.

FWIW, enableHastePackages is default-off from Metro 0.79, so hopefully these cases of unintentionally resolving via Haste should go away, but this is a good correctness fix nonetheless.

I'm wondering if we need to update the documentation based on this change 🤔
