chore: carry the RPC-02 deadline-race test fix and re-pin the template

The synced suite contained an assertion that pinned one of two equally
configured deadlines, so it passed alone and failed in a full parallel
run. Fixed upstream and carried here with the template pin moved to
`a0fbafb`.

Three consecutive runs of the 27-file set that reproduced the failure now
pass at 485 tests.
