I tried to insert a panel we already have but the endpoint failed with IntegrityError.
Input data:

{
    "name": "Prenatal",
    "description": "Prenatal",
    "is_visible": 1
}

The endpoint first updated is_visible from 0 to 1 and the description to the one I inserted in the input data, then it returned a failure:

IntegrityError at /gene2phenotype/api/create/panel/
(1062, "Duplicate entry 'Prenatal' for key 'panel.name'")

The endpoint tried to insert the panel again.

If the panel is already in the database the endpoint should return the message "Can not create an existing panel". We don't want to update an existing panel when creating a new one - this could lead to us updating a panel by mistake.
