[Patch proposed] Social Event Invite throws 403 if Organizer isn't enrolled in the event.

Problem/Motivation

Social Event Invite throws 403 if Organizer isn't enrolled in the event.

Steps to reproduce

1. Create Event
2. Do not enroll
3. Try to Invite users via email

Proposed resolution

profiles/contrib/social/modules/social_features/social_event/modules/social_event_invite/src/Form/EnrollInviteEmailForm.php:293
InviteAccess() runs social_event_manager_or_organizer(), but doesn't pass $node as a parameter for check, thus - false positive 403 unless organizer is enrolled.

Remaining tasks

User interface changes

API changes

Data model changes
