Description (partial)

Sensor is unable to register with secondary DC during HA synchronization, secondary DC complains of "name is too long - please register by IP address"

I reproduced this by doing the following:

1. Register sensor to DC (not HA) using IP address.
2. Change device name to something longer than 39 characters in device config UI. 
3. Apply device config.
4. Establish HA with a second DC.
5. Wait for HA synchronization. 

Actual Result: Sensor registration to secondary DC will fail with error "name is too long - please register by IP address"
Expected Result: Sensor registration should go through since the IP address is known
