LP#1892435 Splash page catalog searches don't work with spaces

On older versions of Apache's mod_rewrite, splash page catalog
searches are escaped in JavaScript and escaped again during the
redirect to the Angular locale path, so searches with special
characters result in a search that's still encoded.

Test on Ubuntu 16.04.7, Apache 2.4.18, EG 3.6+. A splash page
catalog search for Harry Potter results in a search for
Harry%20Potter.

Add the NE (noescape) flag to the Angular locale path redirect
in /etc/apache2/eg_vhost.conf as indicated in this example file.
A splash page search for Harry Potter then works as expected.
