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.
This change makes skipping index efficiency more obvious, changing this:
```
Selected 30 parts by date, 30 parts by key, 592 marks to read from 541 ranges
```
Into this:
```
Selected 30 parts by date, 30 parts by key, 48324 marks by primary key, 592 marks to read from 541 ranges
```
This change makes skipping index efficiency more obvious, changing this:
```
Index `idx_duration` has dropped 59 granules.
```
Into this:
```
Index `idx_duration` has dropped 59 / 61 granules.
```
