Test fails: Given this user has been created using the occ command

[phil-davis]

If the user has a mixed-case username, e.g. https://drone.owncloud.com/owncloud/user_ldap/2718/48/11

  Background:                                                    # /var/www/owncloud/testrunner/apps/user_ldap/tests/acceptance/features/cliProvisioning/groups.feature:7
    Given the administrator has invoked occ command "group:list" # OccContext::theAdministratorHasInvokedOccCommand()
    And this user has been created using the occ command:        # OccUsersGroupsContext::theseUsersHaveBeenCreatedUsingTheOccCommand()
      | username | displayname  |
      | Alice    | Alice Hansen |
      User: /var/www/owncloud/server/Alice was not created
      Failed asserting that false is true.

And the message User: /var/www/owncloud/server/Alice was not created is also strange - it should just say User: Alice was not created

The relevant code was added yesterday in #37839

Actually it could be made much simpler...
