[IMP] web: action manager: restore action

When clicking on the breadcrumb to come back to a previously loaded action, the
restore() function is called. With this rev, this old action is shown only once
the Deferred returned by the optional on_reverse_breadcrumb callback is
resolved, i.e. when the action is ready, as it should be.
