@maznag something wrong. Can you rebase?

@maznag something wrong. Can you rebase?

@DanielFran Ooops ! sorry, I completely create new branch from my last commit before previous rebase and do new rebase. I don't know what happened on my last rebase :-). I think everything is ok now

[DanielFran]

@maznag By mistake, I send you the index.js path to server generator instead of entity-server generator.
I fixed the removal of SortToSortBuilderListConverter class directly in your branch

[DanielFran]

Thanks @maznag for the contribution

[maznag]
