PyList.indexOf() and PyTuple.indexOf() fail due to not wrapping the
incoming Java object before passing to the indexOf() method of the
underlying container.

tests/java/javatests/ListTest.java contains a test method called
indexOf() to test this method, however, it is not called by testAll();
it is never used.

Please find attached a patch that:

- renames ListTest.indexOf() to ListTest.test_indexOf()
- calls ListTest.test_indexOf() from ListTest.testAll()
- Fixes PyList.indexOf()
- Fixes PyTuple.indexOf()

Passes regression tests.
