t.throws exception when it doesnt throw

[ccorcos]

with the following file:

import test from 'ava'

test('foo', t => {
  t.throws(() => {})
})

I get an error:

❯❯❯ ava src/pcombs3.test.js

  2 exceptions

Hm, weird. This is what I'm getting with your exact code and environment:

1 failed

  foo
  Missing expected exception..
    Test.t [as fn] (test.js:4:4)

hmm I just realized I was pull the magic assert branch locally so maybe that was being use rather than the global ava. things seem to work now...

Yes, I've confirmed it's an issue with the magic-assert PR.
