[mail] Refactor queue for easier maintenance, use name

We thought the name parameter was the account name to be shown in the
plugin, but it is the contents of the "From" email header instead.

While changing that, we also update the code to better match the open
Pull Request upstream that adds the update-account to the mail plugin
for nextcloud.
