Dev/rspec puppet 1 0 should compile

I have a module that depends on `postgresql::server` and if I add `it { should compile.with_all_deps }` to my units test it fails with `expected that the catalogue would include` once I include `postgresql::server`. So I tried the add `it { should compile.with_all_deps }` in the unit tests of `postgresql::server` and I notice the same issue. I can't figure out whether it is a bug in `rspec-puppet` or `puppetlabs-postgresql`.

This PR shows the issue but does not fix it.
