Fix manual editing of integration_test_methods.dart.

Fix manual editing of integration_test_methods.dart.

In commit 9ad256cf18bc086e27a32e0e5fa8a6a694a36d1a,
integration_test_methods.dart (an auto-generated file) was edited
manually.  The only necessary changes were to imports--the other changes
were the result of sorting declarations and running the formatter.

This CL replicates the necessary changes in the code generator and
re-runs it, un-doing the other changes.  This should fix the test
"pkg/analysis_server/tool/spec/check_all_test".
