The Schematron XSLT built in Jing as an `/..` XPath expression which always evaluates to the empty sequence. Saxon 9.8 consequently raises a SXWN9000 warning, when the validators are created (statically, during EPUBCheck's intializations). This PR initalizes Jing's transformer factory with a static error listener that ignores this warning. This is tested as an integration test (since the warning is produced on the standard error stream at initialization time), run via the Maven failsafe plugin. Fixes #859
