Short description of error
[Please fill out a short description of the error here]

Currently Spin and Spin Duplicate does the exact same thing. They rely at the same operator, have the same tooltips and the same default settings.

I consider this a bug since i think that the Spin Duplicate was meant to create duplicate geometry. And this means to have the Duplicate checkbox ticked by default in the Adjust Last Operation panel. But it is not. As told, the settings are identical, both tools does the same at the moment.

Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]
[Based on the default startup or an attached .blend file (as simple as possible)]

Open Blender, enter Edit mode, test the Spin tool, check its settings in the Last Operation panel. Then do the same with the Spin Duplicate tool.
