The fixture now includes the queries returned directly from the child devices which is stored under child_devices along with valid device ids.
Also fixes a bug in the test_cli.py::test_wifi_scan which fails with more than 9 networks.
In order to support the ks240 which has children for the fan and light
components, this PR adds those modules at the parent level and hides the
children so it looks like a single device to consumers. It also decides
which modules not to take from the child because the child does not
support them even though it say it does. It does this for now via a
fixed list, e.g. `Time`, `Firmware` etc.
Also adds fixtures from two versions and corresponding tests.
