Cannot upload products with the same name

[Quenty]

Describe the bug
Mantle will fail to upload a product with a same name, if it already exists. This is a problem because if you lose your Mantle deployment data (or more likely, Roblox failed to

To Reproduce
Steps to reproduce the behavior:

1. Deploy mantle with products
2. Delete cache
3. Try to deploy again

Expected behavior
It would be awesome if Mantle either renamed the offending product, or used that product as the product in the deploy, or automated it in some way. This would also probably stabilize importing mantle configs from existing places.

Environment (please complete the following information):

• OS: Windows
• Mantle Version: 0.10.8

Additional context
This occurs when Roblox 500 errors, but we should probably work around it.

This is a really interesting one. I'll think a bit more about a graceful way to handle it.
