[Transform] fixes tests which might fail due to auto-stop (#47867)

Batch transforms automatically stop after all data has processed, therefore tests can not reliable test the state. This change rewrites tests to remove the unreliable tests or use continuous transforms instead as they do not auto-stop.

fixes #47441
