Bugfix UART sensor MUX channel selection after sleep:
In case only one UART sensor is connected to the MUX, to a channel other than 0 then the sensor operation could fail in case the initial mux address selection was not successfull. To fix this problem the MUX address is selected again in case a timeout occures during sensor setup.
