Non-existing repository throws nasty error

[drag0nsden]

When I try to ensure a repository (either absent or present) that does not exist in Satellite (anymore), Puppet fails the entire catalog with:
Failed to apply catalog: undefined method 'intern' for nil:NilClass
No mention anywhere as to which class produces the failure. Took me a few hours to sort it out.
Reproduce-able with declaring any rhsm_repo resource, with a repository that does not exist, for example:
rhsm_repo { 'myorg_Puppet_Puppet4': ensure => present, }
The module should either fail, or warn that the repo does not exist, allowing the rest of the run to complete.

This is fixed by the changes from #81 ; the bug was introduced by the Rubocop clean up
