osm filename in submissions json doesn't match filename on server

[danbjoseph]

example

• this data object from http://omkserver.com/omk/odk/submissions/pois.json

{
  "start": "2016-03-20T14:46:48.991Z",
  "end": "2016-03-20T14:49:15.987Z",
  "today": "2016-03-20",
  "deviceid": 9.9000696426321e+14,
  "osm_poi": "0590a8eccbecd1c444a5457f39b48037f2727f55.osm",
  "form_completed": "2016-03-20T14:49:15.987Z",
  "meta": {
    "instanceId": "uuid:b0e8e3e1-447b-4022-a36a-06ead8e5b391",
    "instanceName": "pois",
    "formId": "pois",
    "deviceId": "imei:990006964263213",
    "submissionTime": "2016-03-21T14:53:26.498Z"
  }
}

• but when looking at the instanceId location on the server http://omkserver.com/omk/data/submissions/pois/b0e8e3e1-447b-4022-a36a-06ead8e5b391/ the .osm file at has a name of fdc0b6f6446c56d41e6bf8d0e977e527645ffa47.osm and not the above value for "osm_poi"

another example

"x": {
    "osmsurvey": 2,
    "numhealth": 1,
    "commrepeat_count": 1,
    "commrepeat": {
      "osm_poi": "311d779e8cc3a8e75e1dfcd3e1f7c1d007d3e53c.osm"
    }
  },
  "meta": {
    "instanceId": "uuid:a71c8f7d-e95c-4405-85e6-04b4016f70bb",
    "instanceName": "Liberia_Community_Survey_v18",
    "formId": "Liberia_Community_Survey_v18",
    "deviceId": "imei:357835070235641",
    "submissionTime": "2016-04-03T13:00:51.532Z"
  }

• survey data: http://omkserver.com/omk/odk/submissions/Liberia_Community_Survey_v18.json
• instance Id location: http://omkserver.com/omk/data/submissions/Liberia_Community_Survey_v18/a71c8f7d-e95c-4405-85e6-04b4016f70bb/
• file name in data object from survey json: 311d779e8cc3a8e75e1dfcd3e1f7c1d007d3e53c.osm
• file name at instanceId location on server: 611ce9aa24245d123042f174beb536946d89eb90.osm

another slightly different example

"x":{  
   "osmsurvey":2,
   "numhealth":1,
   "commrepeat_count":1,
   "commrepeat":{  
      "osm_poi":"null.osm"
   }
},
"meta":{  
   "instanceId":"uuid:f34bf349-69d8-44b8-9d0d-4e3cfa89c4ae",
   "instanceName":"Liberia_Community_Survey_v18",
   "formId":"Liberia_Community_Survey_v18",
   "deviceId":"imei:357835070234420",
   "submissionTime":"2016-03-22T15:22:16.352Z"
}

• filename listed as null.osm in the submissions json as seen above
• but a legitimate osm file exists at http://omkserver.com/omk/data/submissions/Liberia_Community_Survey_v18/f34bf349-69d8-44b8-9d0d-4e3cfa89c4ae/
