Connection errors in Console after I used remote agent host / ssh a long time ago once

* Some time ago I used remote agent host via ssh to localhost
* Since then every time I open the Agents Window these errors stream in
* It was not clear to me that I was setting up a "permanent" connection
* I found that I can remove this from the workspace picker dialog via the `x` but it was not clear to me
* I suggest to move these connection to a different area in the UI, perhaps in the settings at the top?
