v0.7.2: Formatted mail address handling regression fix

Welcome to go-mail v0.7.2!

Unfortunately with the v0.7.1 vulnerability fix, a regression was introduced when formatted mail address with full name ("Toni Tester" <toni.tester@example.com> were used, resulting in only the mail address (<toni.tester@example.com>) being handed over to the SMTP client. This bug was spotted and reported by @NCRonB in #497 - thank you very much for the report.

Sorry for any incovenience this might have caused!

What's Changed

• Refactored address handling for improved consistency and formatting by @wneessen in #498
