Object table has tid field in extra_fields

[JavierArredondo]

The problem is this line:

ingestion_step/ingestion_step/step.py

Line 265 in e49389d

response["tid"] = df_min.tid

Where we store the discovery telescope. we want to save all tid?

Also we repeat the field _id into extra_fields.

    "_id" : "AL21kmlwxleekvmrs",
    "aid" : "AL21kmlwxleekvmrs",
