Error 'You cannot specify more than one of content, source, target' using >=v3.0.7

[krzyzan]

Using saz/sudo v3.0.7 following snippet:

sudo::conf { 'operations':
source => "puppet:///modules/${module_name}/sudo/operations",
}

causes puppet error:

Error: Failed to apply catalog: Validation of File[10_operations] failed: You cannot specify more than one of content, source, target at /etc/puppet/environments/yyy/modules/sudo/manifests/conf.pp:104

Apparently it is caused by merging PR #77.
After this PR if $content_real => undef then content => "undef\n" which is incorrect.

@krzyzan Can you give the current master a try, if the problem is solved for you?

[krzyzan]

Your changes resolve the problem.
Tested undef, array and string cases.
Please release 3.0.9 shortly.

[saz]

It's already released.
