Feature with null id, null geometry and empty properties

[wazolab]

Problem

Some entries contain a feature with id: null, geometry: null, and only { links: 0 } in properties. All other expected fields (objtype, tags, username, version, created, deleted, id) are missing.

This crashes the LoCha component in transformFeatures and in rendering components that expect these fields.

Example

/api/0.1/projects/espana_navarra_aquitania_emergency/changes_logs.json, entry [45]:

{
  "id": null,
  "type": "Feature",
  "geometry": null,
  "properties": {
    "links": 0
  }
}

The entry has 34 features total, only this one is malformed.
