Remove sorting of users in js, rely on server side

[jvillafanez]

Description

Previously, users where sorted in the server alphabetically (by displayname it seems), and then the js code sort them again by username with a natural sort. This is weird because the next bunch of user might not be added at the bottom of the list as it's expected, and it might appear at the beginning of the list.

We'll rely on the server to sort the results, so the client will just need to append the results at the end of the list.

I guess we should try to get this in the 10.13 release given that owncloud/user_ldap#796 will be included in user_ldap 0.18.0 and that this app version will be bundled in core 10.13. So if we not merge this, anyone using 10.13 + user_ldap 0.18.0 will notice inconsistent behaviour between LDAP groups and all users sort order.

@jvillafanez merge this or are tests still needed?
