Before this commit, if we have for instance 3 tasks called A, B and C
where A depends on B and B depends on A then we have a cyclic dependency.
Another example with the same tasks, we can have a cyclic dependency if
A depends on B, B depends on C and C depends on A.
This commit checks we have no cyclic dependencies when the user adds a
dependency on a task.

Many2many field will contain the tasks which the current task depend on.
In the form view of project.task model, these fields are added.
