Tonya Mork c64c2d77aa Tests: Fix "null to non-nullable" deprecation notice in Tests_Admin_IncludesPlugin::test_get_plugin_files_folder().
The `Tests_Admin_IncludesPlugin::_create_plugin()` expects the first parameter to be a text string to be written to a plugin file using `fwrite()`.

Passing null causes a `fwrite(): Passing null to parameter #2 ($data) of type string is deprecated` notice.

Ref: https://www.php.net/manual/en/function.fwrite

Follow-up to [31002]. [41806].

Props jrf, hellofromTonya.
