If device offline is when it's deleted it will try/fail to connect forever if restarted

### Current Behavior

Device continues to run instance snapshot even after it's been deleted if started after being deleted in the forge app.

### Expected Behavior

Device Agent should check in with forge app (if MQTT connection fails if using MQTT comms) via HTTP and get notified if device has been deleted.

### Steps To Reproduce

Create device,
Add to instance
Add Snapshot
Stop device
Delete Device
Start Device
