Fix ID checks for scene/group

[Nerivec]

From Zigbee spec:

3.7.2.4.1 Generic Usage Notes
Scene identifier 0x00, along with group identifier 0x0000, is reserved for the global scene used by the OnOff cluster.

Since Philips devices appear to require usage of scene ID zero with non-zero group IDs, I'm assuming the spec has to be interpreted that way, and not just "prevent usage of scene ID zero".

Also got rid of a few more hasOwnProperty that don't check for undefined.
