Permissions: Sync BodySensors/ReadHr permissions on app install.

If either permission is not granted, revoke the other one. This forces the user to re-grant the permission with the new scope. Also validates that the body-sensor background permission is only granted when the foreground permission is granted as well.

This helps to ensure that as apps are installed on the latest platform that they can continue using both new health and legacy body sensors permissions together in a backwards compatible way.
