[server/sources] make sure entity._cw is a Connection before calling Storages
The storage callbacks don't get an explicit Connection objects, so they
go through entity._cw to access the repo and schedule operations. Since
that entity object comes out of the entity cache, its _cw may be a web
request instead of a Connection. So fix it up around the storage
callbacks.
