request #7503: CI job bad parameters with svn

Now instead of trying to launch the job with this url:
http://jenkins.les.internets/job/Steeve/buildWithParameters?param=value/build?token=other

it will do
http://jenkins.les.internets/job/Steeve/buildWithParameters?param=value?token=other

Of course it still works without parameters:
http://jenkins.les.internets/job/Steeve/build?token=other
