[FIX] mail; hr: restore faster and more accurate mention suggestions

The code from v13 used to look for partners in JS before making the RPC, which
was much faster, and also gave better results by returning partners that were
already known and therefore more likely to be selected.

The same logic is reintroduced here, and further improved to take into account
all known partners and sort them according to the likeliness they will be
selected based on various criteria.
