[FIX] mail: correctly fetch customer data when sending invite

Currently when inviting someone on a document all recipients are considered
as standard customers. It means access buttons are not displayed and
addon specific behavior not really triggered.

This commit makes use of ``_get_recipient_data`` tool method allowing
to categorize recipients in groups and display buttons and action links
like other post on documents.
