Renaming machine in machine detail page preserves previously buffered information

Cathy tried renaming a host in the machine details page. The new name was not available. When she hit the REFRESH button, she expected that the details on the machine would be cleared, but they were not. There was an error message that said it failed to refresh, but the previously collected details were still listed for the non-existant machine.

I think hitting REFRESH should zero out the details if the machine is unreachable.
