Elliot Winkler ae9bf4a735 Add minimal support for Rails 6
* Add Rails 6 appraisal to start testing against it.
* Fix usage of Module#parent as this is deprecated in Rails 6 in favor
  of Module#module_parent.
* Ensure that we're using the correct version of `sqlite3` and `pg` at
  all times
* When creating classes within tests, ensure that they are removed
  correctly
* Fix detection of has_secure_password in models: Check that
  InstanceMethodsOnActivation is specifically defined, as Rails 6 no
  longer has such a module.
