Fix for getting stuck in heat_8_15 preset

[AnonymousRetard]

Fixes multiple calls to _async_enter_summer_house_mode overwriting stored_data Fixes issue #368

Not well tested yet but I'm currently testing it and it should work based on my previous change which did work.

There might be an even better fix though (maybe "changing" to a setting which is already the same as the currently active one could/should be blocked even higher up?).

What I have tested for more than two weeks is this:

         builder.set_hvac_mode(hvac_mode)
         builder.set_eco_mode(eco_mode)

That definately works, didn't get stuck in heat_8_15 a single time after this change. But then stored_data is not used at all and temperature and other settings are forced to their defaults instead of previous values when leaving summer_house_mode.
