[teleinfo] log display "Invalid input: urms is zero, cannot perform calculations" but there aren't UMRs in historical mode

On OH 5.2.0, with the bridge configured in historical mode, the Teleinfo binding display in the logs ``` [WARN] [org.openhab.binding.teleinfo.internal.handler.TeleinfoElectricityMeterHandler] - Invalid input: urms is zero, cannot perform calculations. ``` but in historical mode, ‘urms’ is not available, according to the Enedis documentation. https://www.enedis.fr/media/2035/download section 6.1.1 This does not seem to affect the plugin’s operation. We just need to remove this notification from the logs.
