Fix CAST(Nullable(String), Enum())
...
The wrapper that is returned from createStringToEnumWrapper() does not
have access to the ColumnNullable (i.e. original column), because it is
converted to nested type in the prepareRemoveNullable().
So add original ColumnNullable into the block in prepareRemoveNullable()
if source type is Nullable and pass this flag to the
createStringToEnumWrapper() to make it know about that fact that last
column in the block is the original ColumnNullable in this case.
And this one looks most sane.
