Java: Imported enums from local dependency proto files cannot be used as repeated members

[loudmouth]

Issue Description

When importing an enum from another protobuf file in the same repo (local dependency) that enum can be used as a member field, but cannot be used as a repeated member field in java_proto_library and java_grpc_library. This issue is reproducible with both versions 5.0.0 and 5.0.1 of rules_proto_grpc_java.

I've pushed a small repo reproducing the issue. This line of code is the source. Changing the usage of the enum to a non-repeated field or commenting it out, the build works, but as a repeated field it fails.

Our project currently is on version 4.4.0 and we are able to build java_proto_library and java_grpc_library with that version when we import enums from dependency protobuf files and use them as repeated members, the targets build succesfully.
