Description

Create cache with atomicity mode CacheAtomicityMode ATOMIC
and perform put remove for one cache entry

 for (int i = 0; i < 10; i++) {

                cache.put(i, new Organization(i, "Organization-" + i));

                if (i % 2 == 0)
                    cache.put(i, new Organization(i, "Organization-updated-" + i));

                if (i % 5 == 0)
                    cache.remove(i);
            }

Actual WAL content loaded by standalone WAL iterator is as follows:

For TRANSACTIONAL AtomicityMode same test is passing.

Reproducing test can be found in IgniteWalReaderTest.java in PR 2797 (IGNITE-6553):
https://github.com/apache/ignite/pull/2797/files#diff-0f9e5c632b02b68d2e958ddc217d48a1

testRemoveOperationPresentedForDataEntryForAtomic fails, but testRemoveOperationPresentedForDataEntry is passing
