`zone.js` supports jest `test.each()` methods, but it
introduces a bug, which is the `done()` function will not be handled correctly.
```
it('should work with done', done => {
// done will be undefined.
});
```
The reason is the logic of monkey patching `test` method is different from `jasmine` patch
// jasmine patch
```
return testBody.length === 0
? () => testProxyZone.run(testBody, null)
: done => testProxyZone.run(testBody, null, [done]);
```
// jest patch
```
return function(...args) {
return testProxyZone.run(testBody, null, args);
};
```
the purpose of this change is to handle the following cases.
```
test.each([1, 2])('test.each', (arg1, arg2) => {
expect(arg1).toBe(1);
expect(arg2).toBe(2);
});
```
so in jest, it is a little complex, because the `testBody`'s parameter may be bigger than 1, so the
logic in `jasmine`
```
return testBody.length === 0
? () => testProxyZone.run(testBody, null)
: done => testProxyZone.run(testBody, null, [done]);
```
will not work for `test.each` in jest.
So in this PR, I created a dynamic `Function` to return the correct length of paramters (which is required by jest core), to handle
1. normal `test` with or without `done`.
2. each with parameters with or without done.
