Issue with sync_command

[VadymMelnychuk]

I discovered next issue
when my HomeAssistant start I see all modes related to my WaterHeater
machMode = [1,2,3]

in settings section this parameter has type 'Range'
However, after I call command startProgram the 'machMode' become like a fixed. Only value '1' allowed
It happens bcs startProgram also has parameter 'machMode' but with type fixed. So, when you sync fixed -> range you do the reset for ranges.

Also i exxtended sync_command with 'to_sync' parameter:

• if to_sync==True -> will sync only mandatory parameters
• if to_sync is list -> will sync only parameters that exists in to_sync list

+2 minor fixes.

• if cannot find parameter - havee to just continue (not return)
• improved virtual 'active' state for water heater
