Pavel Kovalenko updated IGNITE-8544:
------------------------------------
Description:
After exchange is done, we're using initial exchange version to determine
topology version on what rebalance should be finished and save it. After
rebalance finishing we check current topology version and saved version and if
they are equal, we enable WAL, own partitions and do checkpoint. In other case
we do nothing, because of topology change.
In case of exchanges merge we're saving old topology version (before merge) and
it leads to ignoring logic of enabling WAL and etc, because check on topology
version will be always false-negative.
