Addon Domains fail to restore from Account Migration from cPanel

- the documentroot of the add-on domains is not read, so it is in CWP the addon domains are mapped to the homedir of the master-account.
The documentroot can be read in the backup-zipfile in /userdata/<addon-domain>

- the content of this dir (in the zipfile in /homedir/) is also skipped. The directory is created, but the content is skipped completely and the blank index.html of cwp is placed there.
