php 7.1 Issue ApachesolrAttachmentsEntityFieldQuery::finishQuery campatibility

Declaration of ApachesolrAttachmentsEntityFieldQuery::finishQuery(SelectQuery $select_query, $id_key = 'entity_id') should be compatible with EntityFieldQuery::finishQuery($select_query, $id_key = 'entity_id') [warning]
imageinfo_cache.drush.inc:201

This happens when you run drush cc all. Ideally Drupal core would upgrade the call to have SelectQuery, but this could be an api breaking change which they cannot introduce. Thus ideally this module should conform to the existing finishQuery function.
