strange little bug, only_ids parameter for union sometimes returns an extra null profiles in list.

somehow i can't add json data to geni discussion because it has urls.. but there are those key points:
with only_ids:
"children":["profile-125352570",null,"profile-34661681031","profile-34675949355"]
without only_ids:
"children":["<apiurl>/profile-125352570","<apiurl>/profile-34661681031","<apiurl>/profile-34675949355"]

with only_ids:
https://www.geni.com/api/union-39926358?only_ids=1

without only_ids, that is not happening:
https://www.geni.com/api/union-39926358

That is odd - I created a problem report for Geni from your observation. These discussions might not be monitored regularly by their staff.

Thanks for letting us know.
I'll take a look.

I pushed a fix.

Please let me know if that resolves the issue.

at least for that profile, it is now working.
