Description of the bug:
After this commit a3f0bfa, using rules_swift in some cases results in this error:

What's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.
Here's a repro project protorepro.zip. Run USE_BAZEL_VERSION=last_green bazelisk build .... Testing with the commit before that does not have the issue. Using rules_proto @ the current HEAD (71c4fc69900946093ac5c82d81efd19fa522d060) does not fix the issue.
