Allow call `assert_enqueued_with` and `assert_enqueued_email_with` with no block

Example of `assert_enqueued_with` with no block
```ruby
def test_assert_enqueued_with
  MyJob.perform_later(1,2,3)
  assert_enqueued_with(job: MyJob, args: [1,2,3], queue: 'low')

  MyJob.set(wait_until: Date.tomorrow.noon).perform_later
  assert_enqueued_with(job: MyJob, at: Date.tomorrow.noon)
end
```

Example of `assert_enqueued_email_with` with no block:
```ruby
def test_email
  ContactMailer.welcome.deliver_later
  assert_enqueued_email_with ContactMailer, :welcome
end

def test_email_with_arguments
  ContactMailer.welcome("Hello", "Goodbye").deliver_later
  assert_enqueued_email_with ContactMailer, :welcome, args: ["Hello", "Goodbye"]
end
```
