Adjust tests for more specific voluptuous 0.12.1 exceptions

[spacegaier]

Description

The new voluptuous version 0.12.1 provides improved exception messages if an In or NotIn requirement is not adhered to, by listing all the allowed values to help the user. Example:

value must be one of ['Auto', 'Comfort', 'Cool', 'Dry', 'Fan only', 'Frost Protection', 'Heat', 'Night', 'Off', 'Standby'] @ data['operation_modes'][1]

The xknx tests did not yet account for that and were still checking the old messages.
