User Can Add New TV Shows
As a user,
When I am on the TV show list page,
And I click on the "New" button,
Then I should be redirected to a "New Show" page
When I fill in the text box for "Title" with a valid title,
And I fill in the text box for "Description" with a valid description,
And I click "Submit",
Then I should see a success message "Your TV show was created successfully"
And I should be taken to the TV show list page,
And I should see the new show in the list
