fix(smoke): reference response not undefined r in KV/Queues predicates (#209)

Tests 5 (KV) and 8 (Queues) passed a predicate to page.waitForResponse
whose parameter is `response`, but the body referenced an undefined `r`,
so every run threw `page.waitForResponse: r is not defined`
(ReferenceError). `r` is a leftover from renaming the param `r` ->
`response` in #45 that missed these two `.request()` calls.

Latent since #45 (Mar 22) — the smoke test never reached the test phase
until the deploy step was unblocked in #208. With deploy fixed, 9/11
tests pass and only these two failed for this reason.
