[Bug]: Can't change server architecture

[nomorepanic]

What happened?

If I try to change the server architecture, say from CX to CA an error occurs.

What did you expect to happen?

I'd expect the provider to destroy and recreate the server, as it happens with Terraform providers for other cloud platforms.

Please provide a minimal working example

resource "hcloud_server" "myserver" {
-  server_type  = "cx22"
+  server_type  = "cax11"
}
