Panic when creating simple nested dataframe with numpy

[coastalwhite]

Checks

• I have checked that this issue has not already been reported.
• I have confirmed this bug exists on the latest version of Polars.

Reproducible example

import polars as pl
import numpy as np

arr2 = np.random.randint(0, 32, size=(10, 1))
arr2 = np.append(arr2, [[None]], axis=0)
df = pl.DataFrame({ 'x': arr2 }, schema={'x': pl.List(pl.Int8)})

Log output

No response

Issue description

Another, more minimal, example:

import polars as pl
import numpy as np

arr = np.array([[None]])
df = pl.DataFrame({ 'x': arr })
