MCOL-4823 WHERE char_col<varchar_col returns a wrong result of a large table (#2060)

Browse Source 
SCommand StrFilterCmd::duplicate() missed these two lines:

    filterCmd->leftColType = leftColType;
    filterCmd->rightColType = rightColType;

which exist in the parent's FilterCommand::duplicate().

Rewriting the code to avoid duplication by using more inherited
methods/constructors. This reduces the probability of similar bugs
in the future.
