Extraction error when renaming datatype and creating new with same name

[bjarnef]

I noticed an issue when a had a "Icon Picker" datatype instance (based on Media Picker 3), which I renamed to "Media Icon Picker" and created a new datatype "Icon Picker" (based on a custom property editor).

After deployment to Umbraco Cloud environment I got the following extraction error:

I could solved it by doing it several steps:

• Rename "Icon Picker" to "Media Icon Picker" and deploy change
• Create new "Icon Picker" datatype instance and deploy change

However now when a pull the changes from development environment to local environment (on other computer) I get the same extraction errors.

I can solve the extraction error manually on local environment, when I rename the existing datatype "Icon Picker" to "Media Icon Picker" first.

It seems deploy is a bit confused about renaming the existing from "Icon Picker" -> "Media Icon Picker" while creating a new with same original name "Icon Picker".
