test: correct stale #[ignore] reasons

Running the ignored tests shows several reasons naming a blocker the
test never reaches. The plugin hooks in all_functional_test do run, and
what stops both cases is the worker's Composer\InstalledVersions;
class_loader_test stops at include_file, not class_exists;
auth_helper_test's wrapper is ported and the blocker is trigger_error;
composerRequire is ported as __shirabe_composer_require.
