Add New Delivery Service crash on duplicate info

[dangogh]

In UI, select DeliveryServices and then Add New Delivery Service. Fill in only required fields -- for origin url, use something like http://localhost:8080. For Regular Expression, use aa/.* then Save. Again Add New Delivery Service and enter all the same info including the Regular Expression and click Save. You should see an error "There already is a HOST_REGEXP (aa/._xcr.kabletown.net) that maches aa/._xcr.kabletown.net; No can do.". Change the regular expression to something else and Save. You will get the following in a popup rather than a proper error message:
