Workaround to fetch server info in the pipeline

`redis.client.BasePipeline` (and its children) always return itself
except `BasePipeline.execute()` is called. Because `MULTI/EXEC` commands
of Redis does like this. And, `sider.session.Session.client` can be replaced
with pipeline object in the transaction. Therefore, sometimes
`Session.server_version` returns pipeline object rather than a version string.
