This is about https://play.kotlinlang.org/koans/Collections/All%20Any%20and%20other%20predicates/Task.kt. `findCustomerFrom` should "return a customer who lives in a given city". Looking at https://github.com/Kotlin/kotlin-koans-edu/blob/master/Collections/All%20Any%20and%20other%20predicates/test/TestShop.kt#L61, that's `lucas` or `cooper`. However, https://github.com/Kotlin/kotlin-koans-edu/blob/master/Collections/All%20Any%20and%20other%20predicates/test/tests.kt#L24 only recognises `lucas`.
