You should update the output path in the .csproj file of the just created project.
I've attached an image as where to click in visual studio. The example is identical to your situation, only difference is that the desired plugin's name is 'Payments.CheckMoneyOrder' instead of 'Widgets.Test'.
Next, edit the output path as demonstrated in the xml below. In your case, this would mean replacing the 'Payments.CheckMoneyOrder' by 'Wigets.Test'.
