Bug Found: Error in code

Hi Renzo,

I develop a cf7 extension which some of my users have reported an error when using in combination with your mailchimp extension. I have been running some tests on my local server and found an error in one of your files,

PHP Fatal error:  Uncaught ArgumentCountError: Too few arguments to function, 2 passed  exactly 4 expected
Stack trace:
#0 /var/www/html/cf7/wp-includes/class-wp-hook.php(286)
#1 /var/www/html/cf7/wp-includes/plugin.php(208): WP_Hook->apply_filters
#2 /var/www/html/cf7/wp-content/plugins/contact-form-7-mailchimp-extension/lib/functions.php(134): apply_filters('wpcf7_mail_tag_...',...

Your file contact-form-7-mailchimp-extension/lib/functions.php on line 134 calls,

apply_filters( 'wpcf7_mail_tag_replaced', $replaced, $submitted )

however, this filter has now been updated in the contact form 7 plugin and now passes 4 arguments,
File contact-form-7/includes/mail.php line 346.

apply_filters( 'wpcf7_mail_tag_replaced', $replaced, $submitted, $html, $mail_tag );

can you fix this in your code?

many thanks
Vrata
