Using the user object at `/org/freedesktop/login1/User/self` is convenient, but has the caveat that login1 does not emit the `PropertiesChanged` signal for the object. That is indeed logical, as for signal emissions there is no sender that can be used to resolve `self`. The new TimeLimitsManager depends on change notifications for user properties, so stop using the `self` shorthand and instead create the User proxy for the user's UID.
