UpdateReceivedShare of pkg ocm json driver does not actually persist the updated field

[redblom]

Using the ocm share json driver, when accepting an ocm share the state field of the model is not actually updated to accepted (ie. not saved). Although the State field of the retrieved share is updated,

reva/pkg/ocm/share/repository/json/json.go

Line 510 in 31fb861

rs.State = share.State

the mrg model is not. And thus the update is not persisted. And listing the received share still shows it as pending.

This

reva/pkg/ocm/share/repository/json/json.go

Line 495 in 31fb861

rs, err := m.GetReceivedShare(ctx, user, &ocm.ShareReference{Spec: &ocm.ShareReference_Id{Id: share.Id}})

does not return a pointer to the model and thus the model is not updated.
