stabilize is_contract and caller_is_origin

[agryaznov]

Follow-up to substrate#10971

[agryaznov]

I'm currently getting e2e test for this failing (using updated contracts node):

RUST_LOG=info cargo test --features polkadot-js-ui -- contract_introspection

results in error:

thread 'tests::contract_introspection::delegator_works' panicked at 'upload must have succeeded, but events contain only [Event { header: "", status: "balances.Withdraw" }]', src/uis/polkadot_js.rs:417:9

seems like it fails even to upload the contract

Not sure exactly what the problem is.
