issue: when restoring data with `loaddata`, need to change the `LogEntry` to allow creation of new objects

[0xcad]

problem:

when the user wants to restore from a backup, they can't, because the presave handler on LogEntry tries to create a LogEntry item using the default user. however that user doesn't exist because the data hasn't been backed up yet.

fix:

• just add a try statement, or a case for if there are no users, just skip making LogEntries

also todo:

• move the script to do backups to this repo
