Bug 18669 - RewriteCond affecting wrong rule in koha-httpd.conf

One of the RewriteCond directives in koha-httpd.conf was affecting
the wrong RewriteRule after its original RewriteRule was commented out
years ago.

_TEST PLAN_
0) Before applying patch, build Koha from source
    *) make
    *) make install (or make upgrade)
    *) Copy or symlink etc/koha-httpd.conf to your Apache vhost directory
        (and enable if you're on a Debian based system)
    *) Restart Apache
1) Make sure that you have at least 1 bibliographic record in Koha
(URL like this http://server:port/cgi-bin/koha/opac-detail.pl?biblionumber=1)
2) Go to http://server:port/bib/1
3) Note that you get a 404 error
4) Apply the patch
5) Rebuild Koha from source as per step 0
6) Go to http://server:port/bib/1
7) Note that you now see the same page as you would if you went to
http://server:port/cgi-bin/koha/opac-detail.pl?biblionumber=1
