WOC_WRITE_ONLY_COLLECTION_LOCAL false positive if collection is passed to method

[kstarsinic]

Similar to #39:

public void fail() {
    List l = new ArrayList<String>();

    l.add("a");
    l.add(giveMeAString());

    doSomethingWithList(l); // l is not really a write-only collection any more, is it?
}
