Use a non-chunked attribute for non-chunking tests in TestReadInterac…

…tion.

We were using an attribute that led to multiple reports, in a test that only
cares about whether a report is delivered at all.  There's no reason to do that,
and it can lead to some timing-related failures if we don't spin the event loop
long enough to get all the reports.
