Olivier Dony d6e734d436 [FIX] mass_mailing: speed up recipients filtering
Using a `set` to lookup recipients that already received an email is
much faster on average than with a list. `x in list` is O(n) on
average, whereas `x in set` closer to O(1) on average.

Example: for a sample mailing with 50k recipients that is half-through,
filtering the remaining half (25k) took 10s with a list, and 1s with
the set.
