Link editing.js also from an entry point outside the project directory

The path was relative to the URL of the entry point, which works for
adminer/index.php and editor/index.php but not for tests/elastic.php,
tests/sqlite.php and tests/plugins.php, where it pointed to tests/. The file
was not loaded there, so syntaxHighlighting() and loginDriver() were missing.
