"Register using Google" (and probably others) creates xf_ip entry for action "avatar_update" with user_id=0

[Steffen]

Affected version

2.2.15

XF\Pub\Controller::setupConnectedRegistration calls XF\Service\User\Registration::applyAvatarFromUrl which in turn calls XF\Service\Avatar::updateAvatar which finally calls its own writeIpLog method. It seems like at this point in time XF::visitor()->user_id is still 0 which causes entries in xf_ip with action = avatar_update and user_id = 0. This log entry is wrong and probably unnecessary because later on another entry with action = register will be created that has the correct user_id.

This seems like a reasonable fix to me (i.e. don't log IPs on avatar "update" during registration):
