Updates the copyright to 2021 for all files that have a copyright. Files in our source code without the copyright header still do not receive one automatically. Additionally, backlisted files are also excluded.
Previously the copyright of chiliproject which references redmine stated a copyright of redmine up to and including 2017 which is not true for the code we have in here. Because of that I changed that to 2013
* deprecated method
* remove apparently unused methods
* append id desc sorting to work packages
* enforce sorting is applied in query results
* ensure deterministic order in base query
Surprisingly, ActiveSupport does not provide this functionality out
of the box: the Rails `deprecate` macro does not alias.
