instance id / private IP not showing about batchiepatchie

it doesn't seem t be populated for us either, and we created batchiepatchie.

Ok I've never done any go or postgres but I took a closer look at this. I noticed that I was seeing and error in the logfile from the postgres container. It was complaining that it could not insert a null value into one of the tables. So I went to look where the table is defined (task_arns_to_instance_info) and indeed it has as a restriction that both private and public ips cannot be null. Our batch setup (and yours I guess) only uses private ips. Allowing those two fields to take on null values seems to allow the ip fields and the instance id to be correctly populated.

Would you like me to make a pull request with the suggested change?

sure that'd be great. note that it may take me a while to get around to testing and merging it
