Incorrect Method Call in getLabels

[emeth-kim]

There is a minor bug in the getLabels method.

JFastText/src/main/java/com/github/jfasttext/JFastText.java

Lines 108 to 110 in 130e5e0

 public List<String> getLabels() { 
     return stringVec2Strings(fta.getWords()); 
 } 

should be

public List<String> getLabels() { 
    return stringVec2Strings(fta.getLabels()); 
}
