Summary	0006132: Invitations cannot be added to calendar when Participation Role is missing
Description	ICAL invitations cannot be added to the calendar, when the attributes ROLE=REQ-PARTICIPANT and PARTSTAT=NEEDS-ACTION are missing. But both attributes are optional in RFC 5545 (see https://www.rfc-editor.org/rfc/rfc5545.html#section-3.2.16) and will be interpreted as ROLE=REQ-PARTICIPANT and PARTSTAT=NEEDS-ACTION if missing. The component we're using in our CMS (https://kigkonsult.se/iCalcreator/) is removing these attributes as they are not mandatory and default is given. See https://github.com/iCalcreator/iCalcreator/blob/master/src/Util/CalAddressFactory.php#L477-L504 for more information. So please let the user adding an invitation to his calendar, when the attributes ROLE and PARTSTAT are missing too.
Steps To Reproduce	1) Sent a invite with an embedded invitation which contains ATTENDEE;ROLE=REQ-PARTICIPANT;PARTSTAT=NEEDS-ACTION;CN=Jean Dupont;RSVP=TRUE:tout-le-monde@sogo.nu -> adding to calendar is possible 2) Sent a invite with an embedded invitation which contains ATTENDEE;CN=Jean Dupont;RSVP=TRUE:tout-le-monde@sogo.nu -> adding to calendar is NOT possible
