Helpful message about missing trait imports is not produced in every case

[IGI-111]

We introduced a helpful TraitNotImportedAtFunctionApplication error in #5293 but it isn't being produced in every instance of a missing Hash implementation.

For instance this contract:

contract;

storage {
    total_supply: StorageMap<AssetId, u64> = StorageMap {},
}

produces this error:

    Finished dev [unoptimized + debuginfo] target(s) in 0.33s
     Running `target/debug/forc build --path /home/igi-111/test_forc`
