Issue # 114 - add unit test for multi-climate VTherm

without these parenthesis the `action` and therefore returned `hvac_action` seems to be `True` instead of i.e. `heating`
(did not see that when using an underlying homekit devices climate device, but when the underlying was a generic thermostat)

 This thermostat can control 2 types of equipment:
 1. a heater that only works in on/off mode (named ```thermostat_over_switch```). The minimum configuration required to use this type of thermostat is:
-   has. equipment such as a radiator (a ```switch``` or equivalent),
-   b. a temperature probe for the room (or an input_number),
-   vs. an external temperature sensor (think about weather integration if you don't have one)

-   has. equipment such as air conditioning which is controlled by its own ```climate``` type entity,
