This commit refactors the patch function in order to simplify its code
but also and most of all remove the `this._super` bound on each patched
method call.
The patch function now supports the javascript keyword `super` to
get the parent's property.
This removes constraints we had with `this._super`. We had to create a
rather complicated intermediate function to bind `this._super` and this
function was called each time before we called a patched method.
It was annoying for debugging but necessary. Because of this
intermediate function `this._super` was also had to re-bind each time
we entered a patched method which was annoying with async method, we
had to save the parent method in the patch before awaiting its
execution. Finally, not a big issue but still, objects could not have a
`_super` property as it would be hidden in the patch.
