`describe_instances` dies if `instances` argument has length 0. #10

Easy to reproduce:aws.ec2::describe_instances(c()) returns:

Error in names(instance) <- paste0("InstanceId.", 1:length(instance)) : 
  'names' attribute [2] must be the same length as the vector [0]

It is sort of an edge case, but may be common enough to handle instead of throwing an error.
