fix(replica): reconstruct ActiveChain and SnapshotLvolMap while creat…

…ing replica

If a replica's ActiveChain is not constructed while creating it, the mismatch
found by the validateAndUpdate() will result in the error state.

```
....
	newSnapshotLvolMap, err := constructSnapshotLvolMap(r.Name, bdevLvolMap)
	if err != nil {
		return err
	}
	if len(r.SnapshotLvolMap) != len(newSnapshotLvolMap) {
		return fmt.Errorf("replica current active snapshot ....")
	}
