TST: Fix integer ops comparison test

[TomAugspurger]

The op(Series[integer], other) path was being tested twice.
The op(IntegerArray, other) path was not being tested.

Closes #22096

thanks @TomAugspurger

do we have coverage for this anywhere else?

should we make these ops tests more general? (e.g. i think only integer na exercises them now, but in the future would be nice to automatically test).

We have an open issue for writing base tests comparing arrays to {scalar, list, ndarary, series, index}
