__nextcloud: remove --webroot parameter

Because the detection of the webroot is not that good, it was removed.
Now, the object id contains the full path of the nextcloud installation.

This changes the installation process a bit, as it will download the
tarball to /tmp rather the webroot.

Also, this commit contains a bit overhaul work.
