Review comment:
as javadoc https://lightbend.github.io/config/latest/api/index.html
says, it will return false:
```
Checks whether a value is present and non-null at the given path. This
differs in two ways from Map.containsKey() as implemented by
[ConfigObject](https://lightbend.github.io/config/latest/api/com/typesafe/config/ConfigObject.html):
it looks for a path expression, not a key; and it returns false for null
values, while containsKey() returns true indicating that the object contains a
null value for the key.
```
