Prevent execution to stop when pair that doesn't exist encountered about ityfuzz HOT 6 CLOSED

Are you sure this isn't just this problem?:

#64 (comment)

No, this occurs even on blocks synced by graphapi. And my little fix helps in 90% such cases, as some pairs exists for such contracts.

Hey bro, give this PR a try and see if it can solve the problem.#110

Nope. See another example, when it fails with original missing data exception.

Wrapping is not enough, I guess pair oracle should be turned off in case if pair list is empty.
Otherwise pop from empty list happens here in some contracts:
endpoints.rs 948:

let mut peg_info = self
            .get_pair_pegged(token, network, block)
            .get(0)
            .unwrap()
            .clone();

fix #110

The reason for this error is that graphapi returned a value with "null", which caused serde_json to be unable to parse it.

The same question arises in
invalid type: null
Don't show null deps

Thanks a lot
