PC 4.0.0-beta3: Package Control: The library "package_setting_context" is not available for Python 3.8

After updating to 4.0.0-beta3 (from beta2), I get this error in ST console during starting.

Traceback (most recent call last):

AttributeError: 'NoneType' object has no attribute 'run_command'

I've seen ColorHelper throwing NoneType errors various times, already. Haven't had time to dig into it, but I doubt there's something Package Control could do to prevent it.

Package Control: The library "package_setting_context" is not available for Python 3.8

The message indicates at least one package running on python 3.8 plugin_host, which requests package_setting_context dependency.

Nothing to be concerned about. PC just shows the result of checking missing libraries at start.

While Package Control client can handle python 3.8 dependencies, packagecontrol.io requires update to ship channel_v4.json files with required meta data.

This looks good at this moment. Sorry for the false alram 😓
