Fix Slow performance of ConfigurationChangedDataRouter on trigger re-creation with many triggers

[woehrl01]

Fix for http://www.symmetricds.org/issues/view.php?id=2621

I found another possible improvement but maybe some else could fix this, I'm not sure if extending all those methods with a true flag is a great idea. The "bad path" is:

engine.getTriggerRouterService().syncTrigger(trigger, null, false);

public void syncTrigger(Trigger trigger, ITriggerCreationListener listener, boolean force, boolean verifyInDatabase)

There getActiveTriggerHistories gets called for each trigger and shortly afterwards getActiveTriggerHistories(trigger) for the specific trigger. I think that a small refactoring would be useful here.

Sorry for the "big change" in ITriggerRouterService.java it seams there was a line ending missmatch in the base file.
