Test failure on Oracle: test_cursor_contextmanager

[Shai Berger]

On Oracle, we get:

======================================================================
ERROR: test_cursor_contextmanager (backends.tests.BackendTestCase)

InterfaceError: not open

This should be easy to fix - just set Oracle's features.closed_cursor_error_class to InterfaceError and things should work. Could you test that this fixes the issue on Oracle?
