Linus Rath a734d0ade1 fix: always write the contact's full name so vCards carry FN #430
`name.full` feeds the vCard FN, which is mandatory; strict CardDAV
clients such as Apple Contacts drop cards without it. The app left it
out or let it go stale on several write paths:

- the contact form (and "Add to contacts", which goes through it) only
  sent `full` when the optional display-name field was filled in
- editing a card put its stored `full` into that field, so renaming
  the person wrote the old name back as FN
- vCard import dropped FN once it had split it into components

Port the webmail's fix (a210b22e): the form derives `full` from the
name components in display order unless a display name of its own is
set, and the edit form only shows `full` when it differs from what
would be derived, so a derived one is recomputed on every save. Import
keeps FN verbatim whether it comes before or after N, and a card with
N but no FN gets a derived `full` too.
