The command of retrieve device by adb devices is incorrect

[xuanzhaopeng]

Source code : https://github.com/appium/appium-docker-android/blob/master/Appium/generate_config.sh#L44

devices=($(adb devices | grep -oP "\K([^ ]+)(?=\sdevice(\W|$))"))

The reason is when I create a container, there is no "device", it will be "unauthorized"

should be

devices=($(adb devices | grep -oP "\K([^ ]+)(?=\s(device|unauthorized)(\W|$))"))

@xuanzhaopeng Would you like to raise a PR?

I'm not sure, that we should "see" unauthorized devices as soon as we are trying to generate node config from props, that we are requesting from devices, like
os_version="$(adb -s $name shell getprop ro.build.version.release | tr -d '\r')"
This command will fail and we will get a broken config, which will affect tests evaluation
