Skip calibration calculation for 'NO_CALIBRATION' mode

[bueeler]

Motivation:

I am using Devolo Connect (MT02650) thermostat recognized by BT as generic thermostat. As there is already a calibration running in Devolo HC gateway, I set BT to use CalibrationMode NO_CALIBRATION. This did not work at all and wrong values were set to the TRV (mainly as the TRV does not provide measured temperature).
However if CalibrationMode is set to NO_CALIBRATION, no calibration value shall be calculated and temperature set in BT should be applied as entered as target temperature (normal, eco or off temperature).

Changes:

Skip calibration calculation in trv.py for 'NO_CALIBRATION' mode and use target temperature instead.
Fixed if statement in controlling.py for target temperature setting
