[IMP] mail: remove duplicated logs when scheduling activities and improve template

Currently when scheduling activities, duplicate logs are created. Indeed
a message is posted when scheduling an activity, editing it and marking it
as done. This leads to a lot of noise being created on records.

This commit remove logs when scheduling and updating an activity. A sole
message is posted when the activity is marked as done.

Scheduled activity display in chatter is also improved to better
differentiate the user creating the activity from the user who is
assigned to the activity.
