wireproto: rephrase the error message for unknown getbundle parameters In case of an unknown parameter passed to ``getbundle``, the server prints a message and ignores the parameter. This message was misleadingly prefixed with "abort: ". The use of "abort: " here is clearly wrong as nothing is actually aborted and the ``getbundle`` call proceeds without the parameter. The message is now prefixed with "warning: " and rephrased to make it clearer that the parameter was simply ignored.
