Style/ZeroLengthPredicate, accepts length < 1

[dennisvandehoef]

The cop Style/ZeroLengthPredicate allows "bad" length checks.
length == 0 gets reported and should be replaced with empty? but length < 1 is ok.
since length < 1 also is an empty? question, it should report it.

Expected behavior

as it does for length == 0, report it

RuboCop version
