Add request to email.send_confirmation() in ResendEmailVerificationView

[MoBoo]

Why?
Currently the email activation which is send when you request to resend the email verification link, the new link uses the domain specified in Djangos Sites package in the database. This links domain therefore might not be the same as the original email verification link.

For example:
Original email verification link: http://localhost:8000/verify-email/<key>/
Resend email verification link: http://example.com/verify-email/<key>/

This could be easily

Proposed Fix
Add request as parameter to email.send_confirmation() in ResendEmailVerificationView to allow url of the current website to be the target url for the email verification link (see below).

Debugging Trace

• ResendEmailVerificationView (line 127)
• EmailAddress.send_confirmation (allauth/account/models.py line 57)
• EmailConfirmation.send (allauth/account/models.py line 123)
• DefaultAccountAdapter.send_confirmation_mail (allauth/account/adapter.py line 451)
• DefaultAccountAdapter.get_email_confirmation_url (allauth/account/adapter.py line 440)
• build_absolute_uri (allauth/utils.py line 265) (see below)

def build_absolute_uri(request, location, protocol=None):
[...]
    if request is None:
        site = Site.objects.get_current() <-- this is what happens, which fetches the website domain from the database
        [...]
    else:
        uri = request.build_absolute_uri(location) <-- this would be expected, because we could pass the request from the ResendEmailVerificationView and therefore use the domain the user used to request resend

I'm facing the same issue. I'm using the sites framework using SiteManager.get_current() method, that calls SiteManager._get_site_by_request(request) only if request objects is passed. So this endpoint gives me an error, because SiteManager._get_site_by_request(request) cannot be called.
