fix: Make "None" option clickable in select dialog on formatter settings

The "None" option in the select dialog was unclickable because the click handler was prematurely returning when the item's value was falsy. This affected options with a `null` value, such as the "None" option for formatters.

This commit modifies the click handler to allow `null` values to be selected. The handler now only returns early if the item's value is `undefined`.

Also when selected None on formatters settings then delete the key saved in settings for that language, as it is not require in case of null
