Fix creating a new DV in BeforeEach() scope
Fix creating a new DV in BeforeEach() scope

DV is not referring to outer scope variable in BeforeEach(),
instead it creates a new DV bounded to BeforeEach() sope.

This is wrong since in the AfterEach() block the DV is checked
to be nil, if it is nil it's being deleted. Since we don't ever
re-assign the dv variable it is never freed (since it's always nil).
