Trim CREATE_TABLES_ON_STARTUP in the JDBCStateManager

In org.jboss.mq.sm.jdbc.JDBCStatemanager::startService

We should trim the result of properties.getProperty("CREATE_TABLES_ON_STARTUP")
otherwise trailing spaces on something like
CREATE_TABLES_ON_STARTUP = TRUE
will result in the check
"TRUE ".equalsIgnoreCase("true") which is actually false.
