[FIX] mail: easily mention followers and employees in chatter

Revision on https://github.com/odoo/odoo/commit/cd34f6de727d5b3858420cff3c9d3c5995c4e75c

Resulting of the mail JS refactoring, the list of prefetched suggestions
has been changed as follow:

- before: list of list of mention suggestions `{Array<Object[]>}`
- after: list of mention suggestions `{Object[]}`

The change resulted in wrongly thinking that wrapping the list of
suggestions in a list was pointless, thus simplifying it as a simple
list of mention suggestions.

However, because of this change, it has become much harder to
mention employees and followers of documents from the chatter:
it now always fetches all partner suggestions at all time, whereas
before it was suggesting followers, then employees, and finally all
partners based on the input of the user.

In fact, there was a purpose of using a list of list of prefetched
mention suggestions, which is to group suggestions by "priority":
followers first, then employees, and all partners as a last resort.

This commit re-introduces prefetched mention suggestions as a list
of list of partners, so that it re-becomes easier to mention
followers and partners of a document from the chatter.
