Describe the problem

Calling modin.pandas.Categorical on a modin.pandas.Series which is already a category dtype results in AttributeError: 'Series' object has no attribute '_codes'. Might be a trivial issue, but I'm reporting since the behavior is unexpected.

Source code / logs

import modin.pandas as pd
s = pd.Series([1,2,3,4], dtype='category')
x = pd.Series([1,2,3,4], dtype='int')

# this won't fail
pd.Categorical(x, categories=None, ordered=True)

# this will
pd.Categorical(s, categories=None, ordered=True)

Duplicate of #4275. modin.pandas.Series object does not have a _codes attribute, which pandas CategoricalDType code expects when reassigning a categorical to another categorical. Referencing this to the broader empty dataframe issue #4605.
