Merge #19696: rpc: Fix addnode remove command error

a51d0ad2de89b9757d158df95ddeba2bfcb23935 rpc: Improve addnode remove command error message (Fabian Jahr)

Pull request description:

  The `addnode` RPC with the `remove` command parameter is used to remove a node from the "added nodes". It did not have test coverage and in case of failure to remove the node it responded with the confusing message "Error: Node has not been added.".

  This PR adds test coverage and introduces a new error code as well as changes the error message to something that makes sense.
