Duplicate entries returns out of sync error

[arioch]

It's not a bug but it might save ppl some time debugging if it would just say that a module has been define twice.

$ cat Puppetfile
mod 'stdlib',                                                                    
  :git => 'git://github.com/puppetlabs/puppetlabs-stdlib.git'

mod 'stdlib',                                                                    
  :git => 'git://github.enterprise.com/puppetlabs-stdlib.git'

$ librarian-puppet install
Puppetfile and Puppetfile.lock are out of sync!
