fix list type in 2.5.13

[TrueJacobG]

people list is not used, doctors list needs to have type List, because of the type checking

[scordio]

Thanks for pointing this out, @TrueJacobG!

Following the semantics in the example comments, the contains parameter should have been people:

// assertion succeeds as both lists contains equivalent items in order.
assertThat(doctors).usingRecursiveFieldByFieldElementComparator(configuration)
                   .contains(sheldon); // FIXME should be the people list

// assertion fails because leonard names are different.
leonard.setName("Leonard Ofstater");
assertThat(doctors).usingRecursiveFieldByFieldElementComparator(configuration)
                   .contains(leonard); // FIXME should be the people list

// assertion fails because howard is missing and leonard is not expected.
people = list(howard, sheldon, raj)
assertThat(doctors).usingRecursiveFieldByFieldElementComparator(configuration)
                   .contains(howard); // FIXME should be the people list

However, it's not as simple as that since type checking kicks in.

For reference, the usingRecursiveFieldByFieldElementComparator Javadoc is also incorrect.

In light of this, I'm closing this PR in favor of assertj/assertj#3837.
