BufferedDataSet#read_ids expect coherent between #cache and
#to_create, patch removed a record from #cache which was in #to_create
leading to not being able to create new records in editable o2ms:
* The record would be inserted in #cache and #to_create
* The listview would reload the record
- Evicting the record from #cache
- And re-reading the record
- Leading to breakage
Don't evict records locally edited from the cache, the server probably
doesn't know about it (at all) or we can assume the server's outdated,
so the local version remains the "correct" one and there's nothing
more recent to fetch.
