The error is because of an invalid if statement in WPCF7_Sumisssion class:

public static function get_instance( $contact_form = null, $args = '' ) {
    if ( $contact_form instanceof WPCF7_ContactForm ) {
        if ( empty( self::$instance ) ) {
	    self::$instance = new self( $contact_form, $args );
	    self::$instance->proceed();
            return self::$instance;
       } else {
            return self::$instance; //correct return
            //return null; // invalid return as we already have an instance set
       }
    } else {
           if ( empty( self::$instance ) ) {
               return null;
           } else {
               return self::$instance;
           }
    }
}
