Update the tests to run with Dart 1.13.

Used a copy of the certificates we use for testing in the Dart SDK.

This does not affect the dart SDK supported by the package itself.

Debug printing?  Does a context print anything?

https://codereview.chromium.org/1432143003/diff/1/test/utils.dart#newcode94
test/utils.dart:94: client = new HttpClient(context: clientContext);
This is actually OK to call with clientContext null, which does the same as a
missing argument, so the whole if statement can be removed, since the case with
secure=false has clientContext null.

Unless you are always setting clientContext, and need to test the case with it
null or missing.

There are tests which combine secure and non-secure, so I need to do it this
way.
