remote/exporter: Export invert parameter on relays

The invert parameter is currently not being exported on Network HID and
Deditec relays. Since the client is the one responsible for inverting
the signal, and it does not recieve this information from the exporter
(which causes it to default to False), the invert is only working on
local setups and not on network exported devices.
