Possible logic mistake on Kirki_Field class

[Daniel Ortiz]

Issue description:

I was reading through Kirki's code to try to find out another problem (#1425) I'm having, and I found this piece of code:

		if ( is_array( $config_id ) && empty( $args ) ) {
			$args = $config_id;
			$this->kirki_config = 'global';
		} 
		$this->kirki_config = trim( esc_attr( $config_id ) );

(class-kirki-field.php, line 320)
It seems to me that this logic may cause errors if one do what it's actually trying to prevent.
The if statement is verifying if only$args are being passed (no config_id), and set the $this->kirki_config = 'global', but then, when it leaves the if statement, it reasign $this->kirki_config to the output of trim( esc_attr( $config_id ) ), which in the case the user didn't pass it, will be an array and will output an error.
Possible fix would be to put an elsestatement there

		if ( is_array( $config_id ) && empty( $args ) ) {
			$args = $config_id;
			$this->kirki_config = 'global';
		} else {
		    $this->kirki_config = trim( esc_attr( $config_id ) );
		}

I didn't test it, but that'd probably do the trick.

I'd put a PR for it, but I didn't see anybody doing PRs here beside the plugin authors and I'm not sure the proper way to do that. So let me know the guidelines for it, if it's possible
