Debug Bar Compatibility: Check if `class_exists( 'Debug_Bar', false )` is not enough in some scenarios #809

If Jetpack is enabled, it will run class_exists( 'Debug_Bar' ), automatically loading the QM version of that class. Then, when QM checks if class_exists( 'Debug_Bar' ) it will return true (because Jetpack loaded it first) and return early. In that scenario, the Debug Bar compatibility layer will never run.
