 Creating events with Thunderbird the attendees were missing in the
 invitation mail.

 Looking at the events the following difference can be seen:
 iOS:
 {{{
 ATTENDEE;CN=felix@derklecks.de;CUTYPE=INDIVIDUAL;PARTSTAT=NEEDS-
 ACTION;RSVP=TRUE:mailto:felix@example.com
 }}}

 Lightning:
 {{{
 ATTENDEE;PARTSTAT=NEEDS-ACTION;ROLE=REQ-
 PARTICIPANT;RSVP=TRUE:mailto:felix@example.com
 }}}


 in mail.py the following is done:
 {{{

       for attendeeProp in calendar.getAllAttendeeProperties():
             params = attendeeProp.params()
             cutype = params.get('CUTYPE', (None,))[0]
             if cutype == "INDIVIDUAL" :
                 cn = params.get("CN", (None,))[0]
                 cuaddr = normalizeCUAddr(attendeeProp.value())
                 if cuaddr.startswith("mailto:"):
                     mailto = cuaddr[7:]
                     if not cn:
                         cn = mailto
                 else:
                     emailAddress = params.get("EMAIL", (None,))[0]
                     if emailAddress:
                         mailto = emailAddress
                     else:
                         mailto = None

                 if cn or mailto:
                     attendees.append( (cn, mailto) )
 }}}

 But reading RFC5545 there is the following:
 {{{
    Description:  This parameter can be specified on properties with a
       CAL-ADDRESS value type.  The parameter identifies the type of
       calendar user specified by the property.  If not specified on a
       property that allows this parameter, the default is INDIVIDUAL.
       Applications MUST treat x-name and iana-token values they don't
       recognize the same way as they would the UNKNOWN value.
 }}}

 Therefore the following patch should be applied:
 {{{
