Prevent ETS node view error when trying to enable/disable ETS tracing on a dead node #81

It takes some time to clean dead node form a Vizceral graph, so there might be a situation when a user clicks on a node in Vizceral graph and the node is already dead. Click on a node cause ErlangPL try to enable/disable ETS tracing for that node and if it's dead it might be a problem. This PR prevents this kind of errors.
