Fixes following issues.

# NG, should be SparseArray (categorized as API change)
a = pd.SparseArray([1, np.nan, np.nan, 3, np.nan])
type(a.take([1, 2]))
# numpy.ndarray

# NG
s = pd.Series([1, np.nan, np.nan, 3, np.nan]).to_sparse()
s.loc[[1, 3]]
# TypeError: reindex() got an unexpected keyword argument 'level'

# NG
s.iloc[2]
# IndexError: index out of bounds

# NG, must be SparseSeries (root cause of 10560)
type(s.iloc[2:])
# pandas.sparse.array.SparseArray
