new-line-before-expect should not require new line on single block

[felipeissa]

Describe the bug

According to the new-line-before-expect documentation, the following is not a warning:

describe("", function() {
it("", function() {
expect(1).toBe(1);
});
});

However I'm receiving a warning for this line of code, which has the same structure.

of(null).subscribe(() =>
expect(spy).toHaveBeenCalled()
);

but if I add braces, it doesn't fail:

of(null).subscribe(() =>{
expect(spy).toHaveBeenCalled();
});

To Reproduce

create a test which does a subscription with a single line expectation in a body without braces.

Expected behaviour

should not display warning
