Test session should continue with no keybox

Browse Source 
Merge from Widevine repo of http://go/wvgerrit/142149

This CL updates the TestCryptoSession so that it will recover from
initializing without a keybox. This allows unit and integration tests
to be run using a test keybox on a device that does not have any
keybox.
