(PUP-11022) Fix generator type collision

The additional_resource_generator_spec.rb test removes the `generator` type
that both it and the transaction_spec.rb defined. Change the latter to register
a different name. This resolves errors like:

    Failure/Error: Puppet::Type.type(:generator).new :title => "generator" }
      NoMethodError:
        undefined method `new' for nil:NilClass
