This test was introduced in order to debug stuck transactions. The cause was unrelated though.
The test here is flaky, because there is a race condition between setting the stream field in the AbstractResultSet and checking it in the close method. Since the result set is not intended to be thread safe, we will not be synchronizing this variable.

… retry loops (#885)

Both the documentation for `TransactionManager` as well as some internal retry loops wrongly used `SpannerException#getRetryDelayInMillis() / 1000` as input for `Thread.sleep(long)`. The retry delay is already in milliseconds and should not be modified.

Fixes #874

This change keeps Maven 3.6.1 and later from spamming our CI logs with page after page of lists of artifacts it's downloading that makes it much harder to find the actual test output.
