Fix group 0

[alexyao2015]

Describe the bug

Group 0 should modify all lights in all groups. Currently, group 0 gives an error since its not a registered group.

Steps to Reproduce

Expected behavior

core/emulated_hue/api.py

Line 847 in 606f671

group_conf = await self.config.async_get_storage_value("groups", group_id)

Properly handle group 0 by iterating through all enabled lights in all groups.
