Remove eventTracking to fix adblocker issues

Adblockers block eventTracking.js files because they are used to
track the user. This fails and causes all other js imports to fail
and breaks the login page.
This removes eventTracking.coffe.
it should not break anything.

-# For sending event data to metabase and google analytics
-# ---
-# by default,
-#   event not sent to MB.
-#     for MB, add event-tracking-mb='true'
-#     by default, event sent to MB via sendMB
-#   event not sent to GA.
-#     for GA, add event-tracking-ga attribute, where the value is the GA category
-# Either GA or MB can use the attribute event-tracking-send-once='true' to
-# send event just once
-#   MB will use the key and GA will use the action to determine if the event
-#   has been sent
-# event-tracking-trigger attribute is required to send event
