Fix ordering between purging and adding/removing modules for debian

Before, purging files from the `mods-enabled` dir and adding
modules to this dir happened unordered, meaning that some modules are
added before all old modules are purged. Puppet (3.7.2) somehow screws
this up and some modules are not installed that should be.
