fix: update another conformance test to determine if request is full table scan

[danieljbruce]

Summary

The NodeJS CBT client fails the TestReadRows_Retry_StreamReset test because the first ReadRows request contains one empty row range instead of no row ranges at all due to this change. The test should allow this first request for a full table scan to be slightly different from other clients as this was done for the TestReadRows_Retry_PausedScan test.

Alternative considered

If we move the code that adds an empty range to execute after the first request when the first error is handled then TestReadRows_Retry_StreamReset will pass without these changes. This client library change is probably not worth the risk at least until an audit is done that will catch all side effects.
