fix: Reference based offing

[superguigui]

This PR solves the special case when two handlers use two distinct but equal functions.

function a () { console.log('a') }
function b () { console.log('a') }

var emitter = dush()
emitter.on('e', a)
emitter.on('e', b)
emitter.off('e', a) // removes both a and b handler
emitter.emit('e') // nothing happens

The problem was that handlers where compared by string in on function. If instead we use reference to the original handler function the comparaison will still work in our special case.

I also took the liberty of removing the useless check on a .called variable on the once handler wrapper.

This should fix issue #22

Hm, why the heck CIs are missing in the checks ?! :D :D :D

Don't worry, I'll handle all this shit ;d

Oh man I don't know. I ran npm audit fix, maybe I shouldn't have 🤕...
Let me know If I can help !

[tunnckoCore]

Haha, no problem, no problem. We don't need fixes anyway, since we don't have deps, only devDeps which isn't a problem for a bit ;d

But anyway, i'll merge and update everything needed, my current repo boilerplate (e.g. as seen in git-commits-since and parse-commit-message) and design is a lot more easier to work with and everything is automated.
