Fix error flash messages when creating tasks

[mzazrivec]

In several places in our code we use the following logic:

task_id = ems.create_some_kind_of_queue(session[:userid], options)
unless task_id.kind_of?(Integer)
  add_flash(_("Some kind of creation failed: Task start failed: ID [%{id}]") % {:id => task_id.to_s}, :error)
end

This is obviously incorrect: since task creation failed, task_id is not an integer and we cannot treat it as integer in the flash error message.
