Added four cases for early conflict detection multi-writing:

1. COPY_ON_WRITE + TIMELINE_SERVER_BASED MARKER
2. MERGE_ON_READ + TIMELINE_SERVER_BASED MARKER
3. MERGE_ON_READ + DIRECT MARKER
4. COPY_ON_WRITE + DIRECT MARKER

Also all the tests are passed including these new four cases.

I believe this PR is ready for reviewing. PTAL :)
