Clear the correct query cache
This executor currently relies on `ActiveRecord::Base.connection` not
changing between `prepare` and `complete`. If something else returns
the current ActiveRecord connection to the pool early then this
`complete` call will fail to clear the correct query cache and restore
the original `query_cache_enabled` status.
This has for example been happening in Sidekiq:
https://github.com/mperham/sidekiq/pull/3166
We can just keep track of the connection as part of the exector state.
