nobishino ccb0a08221 Fix test: update test to comply with the spec of generated sources
https://pkg.go.dev/cmd/go#hdr-Generate_Go_files_by_processing_source says:

> This line must appear before the first non-comment, non-blank text in the file.

Original test cases fail with the previous commit because test source does not comply with this spec.
So, probably we should update test case to comply with the spec.
(This is a breaking change, though)
