Set mixpanel events for location and notification (BasedHardware#732)

Set mixpanel events for location and notification. This should get
updated whenever the permission status changes. For existing users it
will get triggered if they enabled permissions at any point in their
usage of the previous versions (because the default value is false, and
if they did enable permissions, then the value will be true)
