When running tests from analysis_server using "dart test", the Platform.script is a temporary file and this code fails like: ``` 00:01 +0 -1: FlutterSnippetCompletionWithoutNullSafetyTest | test_snippets_flutterStateless_notAvailable_notTopLevel [E] Bad state: Unable to find sdk/pkg/ in /var/folders/b1/ftm2whhj4mb3_c4nfjhq23z00000gn/T/dart_test.kernel.VYZHoV/test.dart_1.dill ``` This change allows using the working directory to find `pkg` if all of the previous attempts fail, before giving up.
