From Odoo 13.0, the list of answers of a user displays the name of the answer itself, and not its parent's. Answers created directly on a question are given a name, but answers created from a comment are not. This commit fixes this behavior for a better consistancy: all posts should have a displayable name. A migration step on saas~12.5 will populate from their parent's name the existing posts that don't have a name. closes odoo/odoo#45193 X-original-commit: 327079e97d12bf3bfcbc74e78bcc7ebc36149d02 Signed-off-by: Paul Morelle <madprog@users.noreply.github.com>
