hook_uninstall() does the wrong thing with config settings

In #2936338: Unable to install Honeypot, honeypot.settings already exists in active configuration. → , code was added to hook_uninstall() in order to try to delete the Honeypot config settings. Specifically, this line was added:
\Drupal::configFactory()->getEditable('honeypot.settings.yml')->delete();

There are two problems with this:

1) In D8+, config settings are automatically installed when a module is installed and automatically deleted by the config system when a module is uninstalled. In D7, by contrast, system variables used by a module with variable_get()/variable_set() needed to be explicitly deleted on uninstall - because of this many people have the misconception that you have to do the same thing for configuration settings, but that is not so.

2) The added code deletes the configuration "honeypot.settings.yml" - but there IS NO SUCH configuration. The only configuration defined is "honeypot.settings". Because there is no such configuration, this line has never done anything in the past and is therefore it is perfectly safe to remove this line.
