How to reproduce:
- Install contacts
- Go to any contact
- Schedule an activity on the contact by clicking on "Activities"
The flag automated of the created activity is set to True which shouldn't be
the case (you can check either in the DB or by adding the field with studio).
The same happens when scheduling plan, scheduling activities on multiple
records in the view list or a plan on multiple records.
This fixes the problem by modifying the activity schedule wizard so that it
always creates activities with automated flag set to False.
Note that that flags is used to distinguish activities created manually from
those created automatically. Some flows automatically cancel automated
activities (e.g. cancel 'validate my ticket') but those should probably not
cancel user defined activities (e.g. 'ask customer to pay'). That's why we must
ensure that activity created manually have that flag set to False.
