server: Fix bug in /api/event/:id #531

Closed kulla closed 3 years ago

Fixes #519 There are events of the kind taxonomy/term/associate and taxonomy/term/dissociate where the child uuid might be null (This might be due to deleted uuids from the database). Also for some events of the kind taxonomy/term/parent/change the previous or the new parent is set to "no parent" in the database. This might be du to a bug or an old behavior of the Serlo software.

Since this is just an database inconsistency that we didn't handle correctly so far, I'd rather fix that in the db directly, see #533.
