Fixing NuLazyFrame/NuDataFrame conversion issues (#12538) 
# Description

@maxim-uvarov brought up another case where converting back and forth
between eager and lazy dataframes was not working correctly:

```
> [[a b]; [6 2] [1 4] [4 1]] | polars into-lazy | polars append -c ([[a b]; [6 2] [1 4] [4 1]] | polars into-df)
Error: nu:🐚:cant_convert

  × Can't convert to NuDataFrame.
   ╭─[entry #1:1:49]

   ·                                                 ──────┬──────
   ·                                                       ╰── can't convert NuLazyFrameCustomValue to NuDataFrame
   ╰────
```

This pull request fixes this case and glaringly obvious similar cases I
could find.
