Subject: [PATCH] Tries to pick up wrong Pazpar2 address errors for errxml

For the search command those are hidden in masterkey commons pz2client
 under a generic "cannot parse session id".

For other commands it can come back in various shapes and forms -
 for instance as a HTML page with domain name adds.
