When exporting personal data for a user request, if the export fails for any reason, a "Retry" link is displayed inline. However, up to this point, clicking this link performed no action. This change adds the `export-personal-data-handle` CSS class to the link to make sure it's picked up by the same delegated listener as the initial action. Clicking this link will now retry the export.
