deploy_packages.pp correct aem_id handling

[mbloch1986]

The deploy artifacts has a logic inside, which sets the aem_id to the aem_id set in the descriptor file.

Since the descriptor file contains not always a aem_id, it needs to be set whether to the parameter from the hiera file or default 'author'. A realistic scenario where the aem_id is going to be set in the descriptor file is the consolidated instance.

[mbloch1986]

Following code line is infected:

$packages.each | Integer $index, Hash $package| {

$aem_id = $package[aem_id]

$final_sleep_seconds = pick(
  $package['sleep_seconds'],
  $sleep_seconds,
)
