--------------------------------------------------------------------
Fix with test to repro.
Basically ignore the generation value...
I've also added some better debug logging to help operators and us see what's
happening.

> ViewBuilder can miss data due to sstable generation filter
> ----------------------------------------------------------
>
> Key: CASSANDRA-13405
> URL: https://issues.apache.org/jira/browse/CASSANDRA-13405
> Project: Cassandra
> Issue Type: Bug
> Reporter: T Jake Luciani
> Assignee: T Jake Luciani
> Labels: materializedviews
> Fix For: 3.0.13
>
>
> The view builder for one MV is restarted when other MVs are added on the same
> keyspace. There is an issue if compaction are running between these restarts
> that can cause the view build is lost since the builder tracks the max
> sstable generation to filter by when it starts back up.
> I don't see a need for this generation tracking across restarts, it only
> needs to be tracked during a builders life (to avoid adding in newly
> compacted data).
