Fixed: ConfigXMLReader doesn't verify if "transaction-timeout" is set before 
trying to unbox
(OFBIZ-8342)

site-conf.xsd doesn't define transaction-timeout as being mandatory but 
ConfigXMLReader treats it as one and in the absence of the attribute an 
exception is being thrown causing the application to break.

jleroux: I have slightly modified the patch, eventElement.getAttribute never 
returns null, default to empty

Thanks: Valery Chenzo
