Hotfix 1.1.3

[arteymix]

All log.error have been switched to log.warn. I also removed the debug enabled check, since SLF4J can do lazy to-string with parametrized logging.

I introduced the following exception hierarchy:

OntologySearchException (generic, includes the queryString)
└ OntologySearchJenaException (where the cause is a JenaException)
  └ RetryWithoutWildcardFailedException (two JenaException as causes: original and last attempt)

Callers should always handle OntologySearchException which is not necessarily Jena-related. If it is, there are more specialized exception types.

All exceptions include the query string used to perform the search. I try to be careful and never log the query itself because it can be pretty big if many clauses are used. If you need to render the query, just catch the exception and print it somewhere, preferably safely.

Maybe just RetryFailedException would be more appropriate as a name? I'm sure there's more than one way to retry a query.
