Fix a type error that occurs comparing two large maps with `deepEquals`. (#2442) Closes #2442 Avoid inference forcing a `List<Iterable<String>>` which results in a type error inserting a range into a list requiring `List<String>`. Add a test for collection truncating which would have failed with a type error before this fix.
