Subject: [PATCH] [FIX] web: bad conversion from ES6 to ES5

We had to manually convert the unhandled-rejection-polyfill lib,
and we forgot to replace this by self in two arrow functions.
This was causing crashes e.g. on Firefox.

We also forgot some uses of const, which is not really an issue as
const is supported on all browsers, but it is not ES5.

Issue reported on the jquery update pad.

closes odoo/odoo#31658
