Query with Time Tracking is failing depending on how you log work

Steps to Reproduce:

1. Create an issue (e.g. Test1)
2. Add an unreleased version to it
3. Click on Close Issue (but before closing it, add e.g. 10m on the work log)
4. Close the issue.
5. Run the following query:

   project = "YourProjectName" AND status = Closed AND timeestimate is EMPTY AND fixVersion = earliestUnreleasedVersion()

6. Create another issue (e.g. Test2)
7. Add an unreleased version to it
8. Add work log to it
9. Close the issue
10. Run the following query again

    project = "YourProjectName" AND status = Closed AND timeestimate is EMPTY AND fixVersion = earliestUnreleasedVersion()

Expected Results:

1. Both issues should show up when the last query is run.

Actual Results:

1. Only the first issue is shown.

Workaround:
None found at this point.

Notes:
Documentation says that timeEstimate is an alias for remainingEstimate. Therefor, it should search for issues where the Remaining Estimate is set to a particular value (i.e. a number, not a date or date range). Though, when searching for:

project = "YourProjectName" AND status = Closed AND remainingEstimate = 0 AND fixVersion = earliestUnreleasedVersion()

None of the issues created above show up.
