[IMP] [Project.Task] Remove confusing priority field from title.
Description of the issue/feature this MR addresses:
Priority field is two times available in project.task.form view. It's also very confusing having it beside the name field, cause it's very big and people could think it belongs to task name.
Desired behavior after MR is merged:
Just have priority field once in project.task.form view and have the kanban state beside the name field.
