Description

During index redistribution process, a new view is created.
During this creation, old indexes should be released.

But, new indexes are "attached" to the same SSTable as the old indexes.

This leads to the deletion of the last SASI index file and breaks the index.

The issue is in this function : https://github.com/apache/cassandra/blob/9ee44db49b13d4b4c91c9d6332ce06a6e2abf944/src/java/org/apache/cassandra/index/sasi/conf/view/View.java#L62
