tests: fix builder id matching

There seems to have been an error where when checking various forms of builder IDs, the loop would return rather than check all builder IDs for the test.

Unfortunately, this breaks some tests:

1. The multi-subjects were generated at main, not be a particular version. So moved those to noversion: true. If we want to regression test this behavior at each version, I can change that later.
2. The builder ID without the qualified /refs/tags/VERSION, just VERSION does not succeed the Match behvaior.

Merging, @laurentsimon let me know if the intent was to verify builders against https://github.com/slsa-framework/slsa-github-generator/.github/workflows/generator_generic_slsa3.yml@v1.0.0. I think it was, but some things are broken. I'll investigate

EDIT: It does work on the CLI; something it just broken with tests.
