Getting rid of two warnings in tests (#3007)

### Summary

A lot of warnings get fired during test execution. Some of them - the
more important ones - require fixes in the code body (not in tests).
They may manifest for users when they run their code, and we opened
Issue #2764 to eliminate them. Others require fixes only in the tests,
and it's always nice to fix those too.

### Details and comments

Part of #2764.

The following warning is completely eliminated:
```
UserWarning: The <some number>-th circuit has no output classical registers so the result will be empty. Did you mean to add measurement instructions?
```

In addition one of two instances of the following warning:
```
DeprecationWarning: Treating CircuitInstruction as an iterable is deprecated legacy behavior since Qiskit 1.2, and will be removed in Qiskit 3.0. Instead, use the `operation`, `qubits` and `clbits` named attributes.
```
