Description

Current implementation of InsertAttributeTag throws NPE if there is no such attribute and ignore flag is set to true. GetAsStringTag implies not-null attribute while InsertAttributeTag from which it is derived misses check of ignore flag before rendering. Need to add simple check in InsertAttributeTag.render() like it was in tiles-2.0.5:
if (attr == null && ignore) {
return;
}
