Cannot restore content if price is empty

[MichaelNielsenDK]

If the Vendr.Price parameter is not given a value on a product node, we get an error when trying to restore content from Cloud to Local.

It's a minor thing, and can be avoided by making the parameter required and making sure it always has a value, but I figured I'll report it anyway, and let you decide if its something that needs fixing.

Umbraco 8.17.0
Umbraco Deploy 4.4.3.0
Vendr 2.0.4
Vendr.Deploy 2.0.1

Good spot.

I think it's definitely worth resolving so I'll take a look and see what we can do 👍
