[plugins] Integration test failures aren't captured (at least on iOS) #105055
Description
It appears that integration tests somehow regressed in our CI. Example (from https://api.cirrus-ci.com/v1/task/4990437185290240/logs/drive.log):

flutter: Warning: integration_test plugin was not detected.
flutter:
flutter: If you're running the tests with `flutter drive`, please make sure your tests
flutter: are in the `integration_test/` directory of your package and use
flutter: `flutter test $path_to_test` to run it instead.
flutter:
flutter: If you're running the tests with Android instrumentation or XCTest, this means
flutter: that you are not capturing test results properly! See the following link for
flutter: how to set up the integration_test plugin:

flutter:
flutter: 00:01 +3 -1: Some tests failed.
All tests passed.
I'm not sure why the integration test plugin wouldn't have been detected. @dnfield was the flutter test thing a breaking change? I thought flutter drive was supposed to keep working for now.
