Connectors: Drop obsolete is_active-missing test case

The connector registry now defaults plugin.is_active to __return_true when
omitted, so the "is_active missing" scenario can't reach
_wp_register_default_connector_settings(). The remaining returns_true /
returns_false tests cover the gate's actual branches.
