[IMP] project: update chatter when create/change task

Before this commit, when the user changes the task, the chatter is not
updated so we keep the messages of the previous task. Same thing when
the portal user wants to create a new task.

This commit updates the chatter to allow to fetch the messages when the
user changes the task and also disables the chatter when the user is
creating a new task.
