Follow-up PR of https://github.com/odoo/odoo/pull/136308
Commit above simplified code in discuss models so code applies
on records than properties on records. For example, instead of
juggling between persona local id and persona, some code can simply
keep logic on persona without leaking local id.
However the improvements are iterative, and more improvements are
needed to stop using local id. Some code still need local ids.
Commit above mistakenly converts a local id to persona on some code
that still work in terms of local id. As a result, message reactions
were not working properly, notably when adding a new reaction using
click on an existing message reaction of someone else.
There was also a bug in implementation in mock server which made the
test not working. This commit fixes this issue too.
