Add getDefaultTarget to Dispatcher

[timkelty]

Getting the current active Monolog logger is a pain, as you need to look at all the targets (web, console, queue) and get the enabled one. This provides a method to streamline that.

With this, regardless of your context, to, eg, call Monolog\Logger::reset(), you can do:

Craft::$app->getLog()->getDefaultTarget()->getLogger()->reset();

It also renames getTargets -> getDefaultTargets, as it got confusing because was explicitly not a getter for the target property.
