Don't hardcode the global tag in the unit test

[wddgit]

PR description:

The unit test has a problem because it hardcodes the global tag and this can cause failures when records in the global tag are removed from CMSSW. Hardcoding the tag instead is less brittle and should work just as well in this test.

See #28010 (review)

PR validation:

Problem unit test passes with this change. This change does not affect anything other than the unit test.

@ggovi, @silviodonato, @cvuosalo we need this to fully test #31729. If we can get it merged asap would be extremely useful :)

[wddgit]

It's less than 10 lines, trivial and noncontroversial, so it should be easy to review. Still needs db approval. (If it is more convenient, I don't mind if you just include these changes in your PR and we close this one. I'm happy either way)
