Fix for #2863 (calling each on uninitialized tag list)

This is a fix for the core issue of #2863, calling each on a nil tag (instead
of empty) tag list for a resource with no tags, combined with various cleanup
in related code to forestall reintroduction of a similar bug.

* Replace the direct @var access with an initializing getter
* Rename it from @tags_hash to @tags_list since it's not a hash
* Do the same with the otherwise identical params setup.
* Eliminate the now-redundant external initialization for params.
* Remove the parameters method as it was never used and obviously
  faulty (calling a non-existent get_params_hash method).
