Add toBeThenable and ToBeCatchy Matcher

Do you want to request a feature or report a bug?
A feature.

What is the current behavior?
Yesterday I write something like this:

expr
.then(function() {
  throw new Error('the expression did not fail');
})
.catch((reason) =>
  expect(reason.message).toContain(error),
);

I think could be more idiomatic write something like this:

expr.toBeCatchy((reason) => expect(reason.message).toContain(error));

or you can simply write this, if you expect that it should fail every time:

expr.toBeCatchy();

And we can do the same with toBeThenable. If you like the idea I can work on a PR, let me know ;)
