Various fixes

[frankrousseau]

Problem

• Project deletion fails when there is a descriptor tied to a department.
• It's possible to create asset types with the same name if cases are different.
• Bump.sh doesn't accept the open API documentation due to curl examples restrictions.

Solution

• Remove descriptor <-> department links before deleting the project.
• Refuse the asset type creation with name equals whether letters are uppercased or not.
• Remove curl examples and send to the Zou documentation.
