Behaviour change in fire statistics in v8.2.0

[ullumullu]

I've discovered a small regression (?) which seems to have been introduced with #877 affecting disabled breakers.

Before

this.emit('fire', args);

The fire event was triggered for disabled breakers as well.

After

Moving the disablement check before the fire event changes the existing behaviour for disabled breakers.

I am not sure if this change was intentional - however it could lead to unwanted side effects for disabled breakers. Moving the emit call before the disablement check would revert the behaviour to the existing status.
