Incorrect hasName implementation

[g4s8]

Github API returns null as name JSON field if user doesn't have a name, but User.Smart#hasName implementation doesn't check it:

public boolean hasName() throws IOException {
    return this.json().containsKey("name");
}

So when I check that user has a name and then read this name I'm getting an error:

java.lang.ClassCastException: javax.json.JsonValueImpl cannot be cast to javax.json.JsonString
