Title: Please merge and try for a release candidate.

Restored testContext to prior behavior, with exception that cached credentials are nulled on failure.

modified getGoogleCompute NOT to call testContext()

NOTE: if ctx.getRegionId() != null, the connection is not tested, and the credential will not be invalidated. I assume(hope) that this is a test for having already been through this method to avoid excessive api calls.
