Respect pluralize_table_names option when creating views

[flanger001]

References #312

As a preamble, I have followed all the steps in CONTRIBUTING.md and have attempted to change the smallest number of lines of code possible.

This PR allows Scenic to respect the pluralize_table_names option when creating views. Formerly, if pluralize_table_names was set to false, Scenic would still create a pluralized view and migration file, e.g.:

# config/application.rb

Rails.application.configure do
  # snip
  config.active_record.pluralize_table_names = false
end

The generator command:

./bin/rails g scenic:view search

Outputs:

• db/migrate/TIMESTAMP_create_searches.rb
• db/views/searches_v01.sql.

Now, with the aforementioned config, this is our output:

• db/migrate/TIMESTAMP_create_search.rb
• db/views/search_v01.sql.

Updating migrations works as well: ./bin/rails generate scenic:view search a second time will output:

• db/migrate/TIMESTAMP_update_search_to_version_2.rb
• db/views/search_v02.sql.
