Change subject: Remove index named after alias.
......................................................................
Remove index named after alias.
If you pass --rebuild to updateSearchIndexConfig.php it'll remove any
index that exists with a name equal to the alias.
We could do this all the time but deleting things is kind of destructive
so I paired it with --rebuild which is very destructive.
