[PATCH] UnitTestFrameworkPkg/UnitTestLib: Correct dereferred pointer.

[PATCH] UnitTestFrameworkPkg/UnitTestLib: Correct dereferred pointer.

[Guomin Jiang]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2609

The copied pointer (SavedState) will be updated by LoadUnitTestCache
call. But the change of SavedState will not update source pointer, which
is NewFramework->SavedState in this case.
