We're still gating things at the server with trusted testers, but to be able
to do experiments with real apps we need to remove the requirement for the
experimental flag (you can't install apps from the webstore that have the
experimental permission).

BUG=98145
TEST=Should be able to install an app with the 'appNotifications' permission.
