Fixing problems with displaying OAI.
If there is error in xsl, nothing displays. This no longer happens with any available Item (checked in rest-tests).
There were no extensive checks, if the OAI produced is the same (or equivalent) as the one in ufal.
There are however, still some differences in the content.
This PR mainly fixes availability and removal of error 500. The content will need to be fixed later.
