This test could probably be made into a lighter-weight test (possibly even a
unit test) by not using a .crx on disk. See, e.g.
https://code.google.com/searchframe#OAMlx_jo-ck/src/chrome/common/extensions/...
for how to create an in-memory Extension. You can then load it using
ExtensionService::AddExtension.

I reworked the code quite a bit to try to make this work. I can create an test
extension but for some reason "AddExtension" crashes in InitializePermissions.
Is there anything else I need to do to ensure that the 'screensaver' permission
is added and added correctly?

This is what the stack looks like,
 [0x000002700ab0] base::debug::StackTrace::StackTrace()
 [0x0000027271a9] logging::LogMessage::~LogMessage()
 [0x000001e4e155] ExtensionService::InitializePermissions()
 [0x000001e4d72c] ExtensionService::AddExtension()
 [0x00000056a082] (anonymous namespace)::InstallExtensionToDefaultProfile()
 [0x00000056a357]
chromeos::ScreensaverControllerTest_OutOfOrder_Test::RunTestOnMainThread()
 [0x0000021e898d] InProcessBrowserTest::RunTestOnMainThreadLoop()
.

Fixed the tests, they pass now.
