[Tests] Fix inifinite replication of Dart processes in tests

When tests are executed on certain configurations like dartkb or simarm,
the test script is first compiled into a dill file, so the VM command
line for running a test looks like

dart .../generated_compilations/dartkb/foo_test/out.dill

Certain tests have the logic to replace '_test.dart' in Platform.script
with '_test_body.dart' and execute the resulting script.
However, as out.dill does not contain '_test.dart', the script remains
the same after replacement. As a result, test was infinitely re-executing
itself, overloading bots and not making any progress.
