Description

1. Enable Elasticsearch extension, run Syncope with test MasterContent and run reindex task to populate ES cluster with Syncope data.
2. Login to console and go to Realm -> GROUP
3. Search for group artDirector from console, result is empty though the group exists. The same happens performing a rest search to /groups endpoint with a case insensitive fiql name=~artDirector
   Searching by name==artDirector or name==artDirector* works, instead.
