Correct the choice of accessory name

Previously would always select "iSight Camera" as the accessory name, so the configured value would never get picked up.

Note - apart from the obvious - the major downside of this issue is that if you had the plugin running on more than one home bridge instance anywhere in your home kit setup - only the first would ever work, as every subsequent one would have a duplicate name etc.
