Issue Summary

Exporting the data from Jira Service management's assets objects will fail if the filter's AQL contains the ampersand (&) character somewhere in the string

Steps to Reproduce

1. Go to an Assets object schema that has some objects
2. View an object type and filter the objects in it using AQL that includes an ampersand like in the example: 

    "Team" = "Test & Test" 

1. Click in the "Bulk actions" drop-down menu (gear icon), then select"Export objects"
2. Select Delimiter, Encoding and Format values then click in "Export"

Expected Results

 The save file widget should open allowing the user to select the destination for the file containing the exported data.

Actual Results

The following unhandled error message is thrown in the page:

{"errorMessages":[
"Unexpected end-of-input: was expecting closing quote for a string value\n at [Source: (String)\"
{\"iqlSearch\":true,\"iqlParams\":{\"objectTypeId\":\"3\",\"attributesToDisplay\":{\"attributesToDisplayIds\":[\"18\",\"19\",\"14\",\"20\",\"16\",\"17\",\"21\"]},\"page\":1,\"asc\":\"0\",\"orderByTypeAttrId\":\"14\",\"resultsPerPage\":100,\"includeAttributes\":true,\"objectSchemaId\":\"3\",\"iql\":\"\\\"Team\\\" = \\\"Test \";

Workaround

Currently the only workaround to this issue is by avoid using the ampersand character at the IQL string.
