Purpose of the task is to remove the needaction message counter from
kanban view due to below reason:
- The user has access to unread messages on records from the discuss
item in the systray.
- It is irrelevant for user handling notifications through their mail
client
- It is only less UI item to worry about on the kanban views (as
features increase, we need to be careful not to clutter the views)
- The user can still use the message_needaction filter to get records
with unread messages
So in this commit we removed the need action counter from all the
kanban view.
