[Bug] Device SysInfo doesn't update if the device is restarted

We have seen that after a device restart, the related and gathered device SysInfo remains with the old information

Example with SysUptime of a device that has been restarted 2 hours ago:

Device SysUptime, viewed from runtime:
```
SysUptime: 1287583000000000
```

Query to the SysUptime OID:

OID | Type | Value
-- | -- | ---
.1.3.6.1.2.1.1.3.0 | TimeTicks | 705456
