datahub - custom assets from datadir fails if the datadir is not present

[pmauduit]

TASK [apache : copy custom assets from datadir] ********************************
fatal: [georchestra]: FAILED! => {"changed": false, "msg": "Source /etc/georchestra/datahub/assets/ not found"}

I suggest to skip the task when /etc/georchestra does not exist.

that task should be run after deploying the datadir ...
