Resolve 4 failing tests, 3 are tests which failed, then worked and now fail again

[jamesfredley]

4 new failing tests: https://github.com/grails/grails-functional-tests/pull/254/files

3 of these were working and were restored on 10/3/24, but are now failing again. https://github.com/grails/grails-functional-tests/pull/251/files

grails/grails-core@2edb2e3 is the PR which triggered https://github.com/grails/grails-functional-tests/actions/runs/11311524760 which was the first time we saw these 4 failures, actually 8, but 4 are still failing.

There were also two test failures before that one. See https://github.com/grails/grails-functional-tests/actions/runs/11300880337

These runs are automatically triggered when PRs are merged to grails-core and the timestamps can be used to identify what commit on grails-core triggered the failure.
