Description

If a node crashes between the Commit log update and local memtable update of the materialized view the node replica could lose MV data. This is really only an issue for RF=1 since the other replicas will likely apply successfully.

In any case we should fix this so MV updates are always applied even during commit log replay (with care to not re-add the mutations to the commit log).
