Using `set_flash` with the `now` qualifier and specifying `n

Error message

Using `set_flash` with the `now` qualifier and specifying `now` after other
qualifiers is no longer allowed.

You'll want to use `now` immediately after `set_flash`. For instance:

    # Valid
    should set_flash.now[:foo]
    should set_flash.now[:foo].to('bar')

    # Invalid
    should set_flash[:foo].now
    should set_flash[:foo].to('bar').now

What it means
