Reduce the amount of times we add blobs as oracle responses

[andresilva91]

Right now whenever a blob is used, we add that blob as an oracle response. However, in the case of application blobs, we can optimize it a bit by when we're using an application, checking if the execution state has an application state saved for this application. If it does, that means that one of the ancestor blocks already made sure this blob is in our storage. Then we don't need to add it as an oracle response or check if it exists. It will already be there.
If that's not true, add it as an oracle response as before.
