Fixed some URL outputs that used esc_url_raw in places where esc_url should have been used

Certain sections of the codebase utilized the esc_url_raw() function where the esc_url() function should have been used instead. Potentially leading to unsanitized output.

This vulnerability affects the following application versions:

• Contact Form 7 3.6
• Contact Form 7 3.7
• Contact Form 7 3.7.1
• Contact Form 7 3.7.2
• Contact Form 7 3.8
