Geary.RFC822.MailboxAddress: Handle empty mailbox and domain parts better
If an address does not have an `@`, or if the IMAP constructor is called
with empty mailbox or domain parts, then these properties will be empty.
This is not uncommon, especially on UNIX hosts where system accounts
send email.
Ensure this is handled correctly in the constructors and are
round-tripped correctly by `to_rfc822_address` and hence
`to_rfc822_string`.
