[NI] Revise variance calculation method for completion mode

Browse Source 
Before fix only one level of type arguments was used to determine variance of type variable to find out direction requirements.
This incorrect in general case, because outer variance affects subtyping deductions, for example:
Inv<Out<A>> <: Inv<Out<B>> => A <: B; B <: A, despite A and B are in covariant position if only one level is considered
