Allow the same LaunchPhase to be used for both start-date and end-date sunrise

Also changed the name of "verifyRegistryStateAllowsLaunchFlows" to "verifyRegistryStateAllowsApplicationFlows", because there are now launch flows that don't use applications (start-date sunrise).

Finally, added a test to showcase the "super-user" power that EPPs with Anchor Tenants have. There's no change in behavior in that regard in this CL - we just add a test to make it explicit.
