We convert the custom plan implementation to use the generic one. As the
generic one can define plans for multiple model. We use the check
dedicated_to_res_model == 'hr.employee' to activate the specific feature for
hr.employee. Indeed, that field contains the model name when the plan is
applicable only for one model.
We also remove the 'launch plan' button as we can now launch a plan directly
from the activities button in the chatter.
Technical notes:
For the activity schedule wizard, we add the support for active_ids and
active_model as default values for res_ids and res_model because it is used as
link in the chatter to launch the wizard and we want to avoid a big migration
by keeping the link identical (and there are probably no simple solution to
keep the same behavior).
HR CONTRACT
Before the first contract date of the first selected element was chosen to
determine the planned due date if all first contract date were different
otherwise the minimum was chosen. So if the selection included 2 different date
among 3, the minimum was chosen but the first if the 3 were different.
With this change, the minimum is always used to determine the default planned
due date.
