Plugin crashing the homebridge installation
From time to time I'm facing this error that shuts down my homebridge (hoobs) server:

`[Homebridge] [4/19/2020, 7:32:09 PM] TypeError: Cannot read property 'id' of null
    at XiaomiRoborockVacuum.changedError (/home/hoobs/.hoobs/node_modules/@hoobs/roborock/index.js:276:78)
    at module.exports.<anonymous> (/home/hoobs/.hoobs/node_modules/@hoobs/roborock/index.js:368:54)
    at EventEmitter.emit (/home/hoobs/.hoobs/node_modules/abstract-things/events/index.js:155:14)
    at Immediate.<anonymous> (/home/hoobs/.hoobs/node_modules/abstract-things/thing.js:141:14)
    at processImmediate (internal/timers.js:456:21)

Thanx for your help,

Olivier.
