Waiting for lenra-io/client_common#105

I tested this on the main page (store page) of the client but I did NOT test it on an application.
We might need to add some documentation to help test applications locally because it became really tiring to setup an app.
If we could maybe add a mix task to automatically create an app in the database with the proper data and already deployed. We could use an already working deployment from git for that.

Seems OK
