ValueError from `nsdiffs` but not from `OCSBTest().estimate_seasonal_differencing_term`

[ftrifoglio]

Describe the bug

I'm getting ValueError: zero-size array to reduction operation maximum which has no identity from nsdiffs with default test but not from OCSBTest().estimate_seasonal_differencing_term.

nsdiffs with ch test is also running fine.

ValueError: zero-size array to reduction operation maximum which has no identity

To Reproduce

from pmdarima.arima.utils import nsdiffs
import numpy as np
y = np.array([110000., 110000.,  74000.,  60500.,  60500.,  49500.,  60500.,
        60500.,  90500.,  74000.,  74000.,  90500.,  90500.,  74000.,
        74000.,  49500.,  49500.,  40500.,  49500.,  49500.,  74000.,
        60500.,  90500.,  90500.,  90500.,  90500.])
nsdiffs(y, m=12)
# ValueError: zero-size array to reduction operation maximum which has no identity
