[SCIM] PATCH `Add` operation on already exists resource

If an already exists member is re-added an 409 error response with duplicate reference error is returned. According to the Add Operation RFC:

Input example:

{
  schemas: ["urn:ietf:params:scim:api:messages:2.0:PatchOp"],
  Operations: [{
    op: "add",
    path:"members",
    value: [{
      value: ...,
      display: ...
    }]
  }]
}

Some changes have been made in the branch “release/2.0.6”:

• Returns “204” instead of 409
• Add “Any” checks

Hello,

First thank you for your feedback. Indeed, the condition must be updated otherwise unexpected conditions can occurred. We are going to update the branch “release/2.0.6” to fix this issue.

Kind Regards,
