Mocha wrapper appears to be broken

[StoneCypher]

Crap

It looks like the Mocha wrapper is broken.

Justification:

1. Take your example code
2. Change the property to assert that 3 > 5, meaning it should break every time
3. Watch it report pass

Observation:

It smelled funky to me that there was an it/2 in the example code, and also an it/2 inside the wrapper. I've used Mocha for almost three hours now, and my understanding is that its do not nest.

Therefore, I removed the interior it/2 from the wrapper. Suddenly things started working.

I also returned the value of the forAll, pretty much just because.

Suggested remediation:

1. Observe that my garbage fixes it
2. Figure out why
3. Throw my gargbage out, because the author (me) didn't put in any effort
4. Fix it correctly instead
5. Accept that nobody ever does this, ever
6. Merge the PR
