function CommonJavaScriptTestCase::testDeprecatedBrowserConditionalComments

Test deprecated conditional comments are no longer output.

Since Backdrop 1.27.0, the "browsers" option for backdrop_add_js() and backdrop_add_css() no longer outputs conditional comments, because conditional comments only work on IE 4-10 (which is completely unsupported). The "browsers" attribute still exists to prevent IE-only files from suddenly appearing on existing sites.
