Query tool fails when attribute responses include a label of `null`

We have a case where some attributes for e.g. nb:Diagnosis return instances without a label. In this case, the label key seems to have a null value.

Here is an example:

{

    {
      "node_name": "International Neuroimaging Data-sharing Initiative",
      "error": "Bad Gateway: <html>\r\n<head><title>502 Bad Gateway</title></head>\r\n<body>\r\n<center><h1>502 Bad Gateway</h1></center>\r\n<hr><center>nginx/1.18.0 (Ubuntu)</center>\r\n</body>\r\n</html>\r\n"
    }
  ],

    "nb:Diagnosis": [

The query tool cannot handle a null label, because the label is used for several functional things like giving dropdown elements an id, sorting elements, displaying them, and so on.

A short time fix might be to just filter out all the options that have a null label. We probably still want to have a warning somewhere (not sure).

The real fix will be tricky. We cannot rely on nodes having good data, so we have to make the query tool able to deal with things like this.
