StreamQueries does only delete the last scrollid [DATAES-817]

[spring-projects-issues]

sothawo opened DATAES-817 and commented

StreamQueries.streamResults() correctly uses the scroll id from the last response for retrieving the next scroll result. At the end only the last scroll id is deleted.
The correct behaviour would be to delete all the different scroll ids encountered during the whole scroll operation
