"did not create a new index" when running es_create first time

[codekiln]

When DEM starts up, it automatically creates and activates indexes if none are created. This means that if your first DEM command is ./manage.py es_create my_index, the first thing it does is auto-create the indexes, and then when it comes time to actually perform the create action it doesn't find that the index has changed:

$ ./manage.py es_create movies
[2018-11-11 20:21:35.400650]: The doc type for index 'movies' changed; created a new index version 'test_movies-8' in elasticsearch.
[2018-11-11 20:21:35.412470]: For index 'movies', activating 'test_movies-8' because you said so.
[2018-11-11 20:21:35.431213]: The doc type for index 'movies' has not changed since 'test_movies-8'... 
PUT http://localhost:9200/test_movies-8 [status:400 request:0.003s]
[2018-11-11 20:21:35.437138]:   ... did not create a new index.

This task is to ensure this confusing messaging does not appear.
