Improve time-to-completion estimation better in arrayTransfer test.
(Not reviewed; minor, test only, and discussed long ago with @ronawho.)
The arrayTransfer test inherited poor time-to-completion estimation
logic from the many-to-one test. The latter was fixed in #17676. Here,
fix the former similarly. I added some temporary instrumentation and
depending on circumstances saw as many as 100x fewer completion checks
in the course of a run.
