`RSpec/ChangeByZero`'s autocorrection causes syntax error if `by(0)` is split into separate lines

[r7kamura]

I found that if by(0) is split into separate lines, the autocorrection result contains an unnecessary empty line, resulting in a syntax error:

# before
expect { foo }
  .to change(Foo, :bar)
  .by(0)
  .and change(Foo, :baz)

# after
expect { foo }
  .to not_change(Foo, :bar)

  .and change(Foo, :baz)

This can be confirmed by the following test code:
