Log:
Fix StackFrame::GetVariables(...) function that was broken by 261858 when lambda functions were added to Block::AppendBlockVariables(). The Stackframe::GetVariables(...) function should get all variables regardless if they are in scope.
This wasn't caught by the test suite so I added a test for it.
