Fixed sending emails crash on email addresses with display names longer
then 75 chars on Python 3.6.11+, 3.7.8+, and 3.8.4+.
Wrapped display names were passed to email.headerregistry.Address()
what caused raising an exception because address parts cannot contain
CR or LF.

Django 2.2 and 3.0 don't support settings samesite='None' in
HttpResponse.set_cookie() so fix is not necessary and will not be
backported.

Cookies with the "SameSite" flag set to None and without the "secure"
flag will be soon rejected by latest browser versions.
This affects sessions and messages cookies.
