The error is: "Element <input id="pin_code" name="pin_code" type="text"> is not reachable by keyboard"

A guess is that the input is either 1. outside of the viewport, or 2. not
displayed yet.

1. We are hidding #registration-form then show it when we retrieved the
   info (after POST /api/v1/auth/two-factor/registration)
2. Couldn't there be a race condition?
In auth.tt
284                     success: function (data) {
292                         $("#registration-form").show();
And in the selenium test:
$s->wait_for_ajax; # There is an ajax request to populate the qr_code and the secret
Not sure this wait_for_ajax is waiting for the end of success, I don't
think so.

This patch is supposed to fix both theories.

Test plan:
0. Do not apply the patch
1. Edit auth.tt and sleep 1 second before showing the form:
290                         const sleep = ms => new Promise(r => setTimeout(r, ms));
291                         await sleep(1000);
292                         $("#registration-form").show();

You will also need to replace the following line (284):
  success: function (data) {
with
  success: async function (data) {

2. prove t/db_dependent/selenium/authentication_2fa.t
=> "is not reachable by keyboard" error!

3. Apply the patch, keep the sleep

4. prove t/db_dependent/selenium/authentication_2fa.t
=> Tests are passing
