Return RESULT_SERVER_ERROR instead of RESULT_NO_MATCH where appropriate

[Kaljurand]

Original issue 18 created by Kaljurand on 2011-12-18T11:42:32.000Z:

In some cases where RESULT_SERVER_ERROR would be correct to return, RESULT_NO_MATCH is currently returned instead, e.g. when the server returns the results in an incorrect format. (This is actually more of an issue with the net-speech-api.)
