Php errors (repeater and header)

Hi there,

great idea for plugin, and (almost) great plugin! ??
I have some errors to report:

1. When in WooMail Customizer, the footer (in preview) is displaying the following error, along with missing (default) social icon images:
   Notice: Undefined property stdClass::$icon_value in .../wp-content/plugins/kadence-woocommerce-email-designer/kadence-woocommerce-email-designer.php on line 157
2. Also, the Repeater elements (each) (in WooMail Customizer -> Footer -> Footer Social) has the following error notice:
   Notice: Undefined variable: icon_color in .../wp-content/plugins/kadence-woocommerce-email-designer/includes/class-customizer-repeater-control.php on line 197
3. When previewing the email template from WooCommerce -> Settings -> Emails I got this error notice :
   Notice: Trying to get property 'id' of non-object in .../wp-content/plugins/kadence-woocommerce-email-designer/templates/woo/emails/email-header.php on line 31

I hope you’ll manage to correct this issues soon and release un update to make this great plugin even greater. ??

Best regards,
Alen
