Pullrequest

Refactor database structure from (resource)<-[:REPORTED]-(report)<-[:REPORTED]-(submitter:User) to simpler (resource)<-[:REPORTED]-(submitter:User) structure.

Issues

• relates #1707 (closed)
• relates #1708 (closed)
• and relative to PR #1797

Todo

• Cypher commands to convert the data of the database to this new structure. See file deployment/legacy-migration/maintenance-worker/migration/neo4j/dbManipulations/20191011_changeReportNodeToRelationOnly.cql

Additional Informations

• Accidentally included a frontend change for adding the created at to the moderators report list to this PR.
• Removed the limit of the report list length. So we have to add pagination in the future. (talked about that with @datenbrei )
