Fixed inconsistent collective.js.jqueryui with Plone 4.3.1

I had some trouble getting this started when using it for the first time: http://paste.opensuse.org/view/simple/93788101 As it worked fine with Plone 4.2 following the instructions of http://www.bikalabs.com/helpcentre/manual/bika-installation-guides/bika-on-ubuntu-linux/installing-bika-lims-3 it might be this simple version check which makes the whole installation fail early and leave a corrupted Plone installation.
