Fix AR::Relation#cache_key to remove select scope added by user
- We don't need the select scope added by user as we only want to max
timestamp and size of the collection. So we already know which columns
to select.
- Additionally having user defined columns in select scope blows the cache_key
method with PostGreSQL because it needs all `selected` columns in the group_by
clause or aggregate function.
- Fixes #23038.
