AttributeError: '_SeriesFromNest' object has no attribute 'nest_name' #405
Description
Bug report
From @mi-dai. With a specific python environment and the latest nested-pandas 0.6.1, a simple query fails
import nested_pandas as npd

1467 # which means that a nested attribute was referenced. Apply this result
1468 # to the nest and repack. Otherwise, apply it to this instance as usual,
1469 # since it operated on the base attributes.

-> 1471 nest_name, flat_nest = result.nest_name, result.flat_nest
1472 # Reset index to "ordinal" like [0, 0, 0, 1, 1, 2, 2, 2]
