NotificationsIT.simpleNotifications is flickering

Summary of the scenario leading to the flicker

• User 2 follows the entier wiki
• User 1 creates a bunch of pages
• User 2 check the notification counts

When not flickering

• The notification bell display a count red pill, and User 2 is able to get access to the notification counts

When flickering:

• The notification bell does not have a red pill with the count

Hypothesis:

1. something goes wrong when saving the "watch whole wiki" step. Therefore, all the events produces by User 1 are ignored
2. something goes wrong when loading the notification bell and the count is badly loaded or badly displayed
