GoogleComputeEngineServiceLiveTest fails when run on its own.

The test fails sometime when all live tests are run and always fails when run on its own.

My brief (possibly incorrect) diagnosis:
The problem appears to be with cloning TemplateOptions.
Null is compared to Optional.Absent() and an error is raised because they are not equal.

Failed tests:
GoogleComputeEngineServiceLiveTest>BaseComputeServiceLiveTest.testOptionToNotBlock:825 options didn't clone properly
