Automapper for Iteration-IterationVM

Added on Infrastructure the Map creation for both ways:
Iteration-IterationVM and IterationVM-Iteration.

Partial view _List now uses an IList<IterationVM> instead an
IterationsListVM (file deleted).
Removed unused imports where possible.
Automapper for TestPlan-TestPlanVM

Added on Infrastructure the Map creation for both ways:
TestPlan-TestPlanVMand TestPlanVM-TestPlan.

Partial view _List now uses an IList<TestPlanVM> instead an
TestPlanListVM (file deleted).

Removed unused imports where possible.
