Bug in PriceEstimator.find_problems_rank_deficient_matrix, columns are falsely considered good:

matrix = [0, 1]:
good_cols = [True, True]

Both columns are considered good; but only column 1 is good. Price of product of column 0 can not be computed.

Correct result would be:

good_cols = [False, True]
