Successful test prints error

Not sure if that is intended, but the test `testFullyQualifiedTemplateRef2` in `TestTemplateNames.java` prints an error to the console, even though it succeeds. The message is:

```
context [/group/c] 1:1 passed 0 arg(s) to template /a with 1 declared arg(s)
```

which is clear given that the `/a` template expects a parameter, which is not specfied:

```java
@Test public void testFullyQualifiedTemplateRef2() throws Exception {
// /randomdir/a and /randomdir/group.stg with b and c templates
String dir = getRandomDir();
writeFile(dir, "a.st", "a(x) ::= << >>\n");
String groupFile =
"b() ::= \"bar\"\n"+
"c() ::= \"\"\n";
writeFile(dir, "group.stg", groupFile);
STGroup group = new STGroupDir(dir);
ST st1 = group.getInstanceOf("/a");
ST st2 = group.getInstanceOf("/group/c"); // invokes /a
String expected = " bar bar ";
String result = st1.render()+st2.render();
assertEquals(expected, result);
}
```

So I wonder if that is just an oversight and nobody ever cared for it or if that is used in some way outside of this test?
