Fixes TestCheckAndMutateRow_NoRetry_TransientError
Before fix:

    checkandmutaterow_test.go:252:

        	Test:       	TestCheckAndMutateRow_NoRetry_TransientError
--- FAIL: TestCheckAndMutateRow_NoRetry_TransientError 

After fix:

=== RUN   TestCheckAndMutateRow_NoRetry_TransientError
--- PASS: TestCheckAndMutateRow_NoRetry_TransientError (0.01s)

We don't know if the conditional mutation has been applied so we can't retry them.
Updated the retry to match Java's retry settings:
