Error in function router:error-description if 1st parameter is missing

[daliboris]

If the error description is missing, the roaster raises an exception. Maybe it's a problem of the TEI Publisher application (api-dba.xql library).

Example of an internal error that throws the mentioned roaster error (from the eXist-db log file):

@daliboris Hah! Funny, @DrRataplan just reported this error and we fixed it in the most recent release v1.8.3 :tada:
