[cards] bug fix with error card renders

[valayDave]

• Error cards didn't contain a reload token replacement because of which the UI keeps trying to poll for new cards.
• This is not the best situation because the UI will keep refreshing the card constantly until the UI catches hold of the card.
• The UI changes will obviously follow for situations where a data update might be published but a card doesn't end up getting saved because of some data store issue; This PR will fix the bug and ensures that if a error card gets created instead of an expected card then the UI still gets the right reload token.
