> rpc: Block until synced if coinstatsindex is used in gettxoutsetinfo
>
> During initial sync after startup the gettxoutsetinfo RPC will still return an error while catching up. However, after the initial sync the index will not error immediately anymore when it's in the process of syncing to the tip while being called. Instead it will block until synced and then return the response.
