When I try to update suggester index on an install that never had this index before, I get exception:
```
vagrant@mediawiki-vagrant:/vagrant/mediawiki$ mwscript extensions/CirrusSearch/maintenance/updateSuggesterIndex.php --wiki cirrustestwiki

Infering index identifier...cirrustestwiki_titlesuggest_1454353233
Unexpected Elasticsearch failure.
Elasticsearch failed in an unexpected way. This is always a bug in CirrusSearch.

Looks like it tries to recycle index that does not exist. If I disable `$wgCirrusSearchRecycleCompletionSuggesterIndex` it works and then enabling it back works too.
