Keep KService::createInstance error message in KServiceTypeTrader::createInstanceFromQuery

Review Request #107032 - Created Oct. 25, 2012 and submitted

KDE/4.10, master
When KServiceTypeTrader::createInstanceFromQuery fails in KService::createInstance, the error message is currently overwritten by the useless information "No service matching the requirements was found". This patch fixes that to keep the error message set by KService::createInstance and thus give me something more useful like e.g. "Cannot load library /home/milian/projects/compiled/kde4/lib/kde4/ ( cannot open shared object file: No such file or directory)" ' 
changed the header, ran KDevelop with invalid plugins, got actually useful output (see above). Another example that was overwritten as well before this patch:

"Cannot load library /home/milian/projects/compiled/kde4/lib/kde4/ (/home/milian/projects/compiled/kde4/lib/kde4/ undefined symbol: _ZTIN8KDevelop17ITemplateProviderE)" '
