Subject: [PATCH] Add missing semicolons after macro calls

Otherwise I was getting this error:

```

```

From this code:

```
try_migrate_deserializer_chain!(
    chain: [MetadataV1, MetadataV2, MetadataV3],
    error: MetadataMigrateError,
    deserializer: toml::Deserializer::new,
);
```

Presumably because I was using 3 values instead of just 2.
