A Filter's ORDERBY clause is not maintained through REST API

Summary

A Filter's ORDERBY clause is not maintained through REST API

Steps to Reproduce

1. Go to Manage Filters
2. Identify the filterid of any filter which has a column with orderby clause used.
3. Access the filter results through REST API

Expected Results

We should get the list of Issues from this filter, and the order of the issue should also be maintained.

Actual Results

The JSON results of the issue filter are not maintained. The JSON is always ordered by key descending, regardless of the ORDERBY clause in the filter.

Notes

Related to verified bug ticket - https://jira.atlassian.com/browse/JRA-37959

Workaround

There is no workaround, as REST API for JIRA doesn't have an ORDERBY clause for JQL.
