core: SynologyDSMAPIErrorException if no cameras starting 0.116.0

The problem

After updating to HA 0.116.0, the Synology DSM integration no longer works. I was using the integration for monitoring the disks and volumes on the NAS. I receive the following error (note, I do not use SurveillanceStation) ad none of the sensors work anymore :

2020-10-07 19:36:26 ERROR (MainThread) [homeassistant.config_entries] Error setting up entry 192.168.1.2 for synology_dsm
