fix(share/eds): recover Shards immediately

Discovered after looking at CarStore sources(https://github.com/filecoin-saturn/L2-node/blob/f5c5ca0cd8cab27d83424e7a77943f900a4d4105/carstore/carstore.go#L177)
I think it should aid long startup times by recoviring shards immediately, rather than on restart/startup only
