Fix magn4853 List.Map fails on first item

This pull request is to fix defect [MAGN 4853: List.Map fails on first item] (http://adsk-oss.myjetbrains.com/youtrack/issue/MAGN-4853).

It is pretty tricky...For some cases (string value, ``%dot()`` call) we push replication guide to the stack but never use it in the corresponding function, and those replication guides are misused by the other function -- in this case by ``List.Map()``. We need to ensure replication guides not saved in the stack.
