Full-history endpoints return wrong parameters in the response

[bonaparten]

Bug Description

A full-history extraction returns in the response the parameters @snapshotTimestamp and/or @lastEdit if the last edit of the OSM entity happened before the period of time requested.

General Information

• ohsome API 1.4.1
• API instances: remote instance https://api.ohsome.org/v1 and local instance with an h2 file
• Affected endpoint(s) [e.g. /elementsfullhistory{geometryType}]
• Request URL
• HTTP method: GET
• Utilized tool/library for the request: Swagger and cURL

Expected Behaviour

Since the full-history endpoints give the full history of the OSM entities at a given time, @snapshotTimestamp and @lastEdit should not be present in the response.
