Issue1419

In both PyTuple and PyList there is a bug in indexOf since it does not
wrap the argument in a PyObject before calling indexOf in the underlying
List.

On the other hand lastIndexOf in both works properly and the same should
be done for indexOf.

Bad:

public synchronized int indexOf(Object o) {
     return list.indexOf(o);
}

Good:

public synchronized int lastIndexOf(Object o) {
     return list.lastIndexOf(Py.java2py(o));
}

What happens is that PyObject.equals(Object) is always false.

Fix checked into rev6628:

Thanks to Andrea for Patch.

We should add a regression test for this.

assigning to myself as a reminder to get a regression test for this.

Added PyTupleTest and PyListTest to tests/java/ so this can be closed now.
