doc: use precise terminology in test runner

We currently use `resolve` which is incorrect from a technical point of
view in several places in the test runner docs.

For anyone wondering "resolves" means the promise's fate is known by
either settling (becoming fulfilled or rejected) or because it's
assimilating the status of another promise (that may be unfulfilled).
