current trunk head. full cloning a template that is linked to some hosts shows up as success, but details contain errors about applications.

template had single host linked in and another template, which in turn had single host.

judging by the error messages, applications were updated for first level linked host, but errored out for the second level host :
Application 'testapp1' already exist in linked hosts

not sure what's the best course on items and applications, but it should be consistent, and operation that contains errors should not succeed partially and be declared successful in frontend
