Fix for "release => ''" problem in apt::source

[jordansissel]

Looks like the latest(?) version of the puppetlabs/apt module doesn't approve of an empty 'release' but is happy if repos is empty:

The error:

Error: lsbdistcodename fact not available: release parameter required at /home/jls/projects/demo.lo
gstash.net/modules/apt/manifests/source.pp:25 on node ds4172.dreamservers.com

Version info:

% grep version modules/{apt,jenkins}/Modulefile               
modules/apt/Modulefile:version '0.0.4'
modules/jenkins/Modulefile:version '0.2.3'

Here's the workaround I applied to make the correct sources.list file generated with apt::source from your jenkins module

It's not a pull request because I haven't forked this, just imported into my own repo.

sounds like this is related to some of the issues in #23 where they just used a single space for release. But this also works.
