The rpc service has a protection (when used via useService) that
prevents the returned promise from being resolved/rejected if the
component has been destroyed meanwhile.
However, as the FormView still uses the legacy BasicModel, all rpcs
done by its model do not go through our new rpc service. As a
consequence, before this commit, they did not benefit from the
protection. This caused a non deterministic issue in the main flow
tour.
This commit implements a similar protection as the rpc service, but
specialized for the BasicRelationalModel, which redirects all RPCs
done by the BasicModel.
This change highlighted two scenarios where we sometimes performed
RPCs (or could perform RPCs) on a destroyed component. This commit
fixes those as well.
