Purpose of this PR to improve the generic usage of project app

So in this commit done the following changes:
 - when a project is archived, the 'tasks' stat button should
   count/show archived tasks
 - when delete project it's milestone should also be deleted automatically.
 - project.task > blocked by notebook: it should be possible to select tasks
   in projects that are not allowing 'task dependencies'
 - project.task portal form view: hide the description if it is empty
