[API] Image entity endpoint not able to deal with any other field except `geometry`

[Rubix982]

Describe the bug The endpoint 'https://graph.mapillary.com/:image_id', when passed any other field other than geometry causes the API to fail. The error I get is similar to this,

{
   "error": {
      "message": "Tried accessing nonexisting field (altitude) on node type (ChunkObject)",
      "type": "MLYApiException",
      "code": 100,
      "fbtrace_id": "A514B-_ujHi2raqz20DgoGT"
   }
}

To Reproduce Visit the API endpoint at the below link,

`'https://graph.mapillary.com/219262519730517/?fields=altitude,atomic_scale,camera_parameters,camera_type,captured_at,compass_angle,computed_altitude,computed_compass_angle,computed_geometry,computed_rotation,exif_orientation,geometry,height,thumb_256_url,thumb_1024_url,thumb_2048_url,merge_cc,mesh,quality_score,sequence,sfm_cluster,width&access_token=MLY|XXX

Expected behavior A proper GeoJSON to be returned

@cbeddow your thoughts?

Let me know if this is solved, should work since the example was using map features endpoint but was asking for images fields, so need to just use matching field names for map features

This problem arises due to a possible mix of the map_feature_key and image_key. There should be an exception that deals with identifying if the key passed is correct or not
