[Developer] Settings panel dropdown saves string "null" instead of removing parameter

[normen]

Describe The Bug:

When using a dropdown in the settings panel for a non-required string the config.json will store "parameter": "null" when selecting "None" in the dropdown.

To Reproduce:

Use e.g. homebridge-bravia and select "None" as TV input, see here: https://github.com/normen/homebridge-bravia/blob/master/config.schema.json

Expected behavior:

The settigs panel should remove the non-required variables where "None" is selected in the dropdown.

Logs:
