Title: remove String.isEmpty() for Java 5 compatibility

Was testing Slf4jLog under Java 5 but the String.isEmpty() prevented the Log
from being initialized. This appears to be the only Java 6 code outside
PeriodicalLog so it seemed worthwhile to change in order to keep the core
of speed4j working on Java 5.
