Problems if cluster has no connectors

[RTaylorXS]

I tried connecting to brand new Kafka Connect cluster - which had no connectors (yet - wanted to use Kafka Connect U-I to setup first connector...) This did not work - the U-I did not display the cluster at all.

After adding a connector and refreshing, Kafka Connect U-I did display the cluster.

After deleting the only connector in a cluster, Kafka Connect U-I continues to display the cluster in the "Configured Clusters" list. However, the cluster cannot be clicked/selected (circle&slash cursor when hover over it) - preventing you from using Kafka Connect U-I to create a connection in that cluster.

Using latest Kafka Connect U-I via Docker (v0.9.7?) - version number isn't displayed on Kafka Connect U-I web interface or Docker logs.
