#417 carddav does not read the field "notes" but overwrites it

[Jenny]

I use davmail v6.2.2

The Situation is as follows. On one side, Outlook with Exchange Account and contacts in the contact folder. A contact has some text in the field "notes".
On the other side, Thunderbird with carddav account accessing the same contacts folder in the exchange mailbox. The contacts are visible, but the notes field is empty.
-> If I add a note in Thunderbird to the contact, the text appears in Outlook and overwrites any existing one.
-> If I change the text in the field "notes" of the contact in Outlook, the note dissapears in Thunderbird.

In the log I can see, that the VCARD contains the note only when synced from Thunderbird to the Exchange Server but not the other way round.
- getting contact
BEGIN:VCARD
VERSION:4.0
UID:xxx
FN:xxx
N:xxx;xxx;;;
EMAIL;TYPE=work:xxx
REV:xxx
END:VCARD

• syncing contact from thunderbird
  BEGIN:VCARD
  VERSION:4.0
  UID:xxx
  FN:xxx
  N:xxx;xx;;;
  EMAIL;TYPE=work;PREF=1:xxx
  REV:xxx
  NOTE:here is the text I added as note
  END:VCARD

For me that seems like a bug. Can you fix it?
