Fix for undefined device properties

[stratacorps]

The problem is in utils.js, specifically

node-red-contrib-eufy-security/eufy-security/utils.js

Line 21 in cc38cf2

result[key] = value?.value;

So when the transformProperties function is called it replaces all values with undefined. Changing utils.js line 21 to this is a simple fix:
result[key] = value;
