[NC 11 alpha] occ command line tool displays ownCloud instead of Nextcloud

[sndrr]

Steps to reproduce

1. go to the installed NC root directory
2. start the occ command line tool (i.e. sudo -u www-data ./occ)
3. observe that the output uses the wording "ownCloud"

Expected behaviour

When grepping for cloud, it should output with Nextcloud.

user@host:/var/www/nextcloud$ sudo -u www-data ./occ | grep -i cloud
  db:convert-type                     Convert the Nextcloud database to the newly configured one

Actual behaviour

When grepping for cloud, it outputs ownCloud

user@host:/var/www/nextcloud$ sudo -u www-data ./occ | grep ownCloud
  db:convert-type                     Convert the ownCloud database to the newly configured one
