FFaker::HTMLIpsum.fancy_string can return a string with no HTML

[xunker]

I have a case where, given the right random seed, FFaker::HTMLIpsum.fancy_string will return a string with no HTML.

Reproduction with v2.18.0 (ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-darwin18]) (MacOS 10.15.7):

> FFaker::Random.seed = 13 # Thirteen?!? Spooky unlucky coincidence!
> FFaker::Random.reset!
> str = FFaker::HTMLIpsum.fancy_string
# => "Placeat voluptatem alias iusto doloribus voluptatibus adipisci excepturi soluta. Nulla minima ex recusandae quisquam eius. Odit similique maxime sed quis vero aliquam quidem. Sunt ad ut officia nesciunt vitae earum sit deleniti. Esse tenetur perferendis fugit quasi. Reiciendis excepturi inventore ducimus harum numquam. Incidunt aperiam sint occaecati sunt aut. Neque accusantium deleniti provident voluptatibus doloribus. Eligendi doloribus pariatur itaque aspernatur similique. Aliquam enim cupiditate perspiciatis eius officia tempora cumque blanditiis. Error vel non harum sed." 
str.include?('<')
# => false 

All other methods won't have this issue regardless of the random seed used because they explicitly put in at least one HTML tag set via a content_tag_for call.

It's more common than it looks. The same output can be seen using a lot of other seeds (97, 176, 197).

Should be fixed after #516 PR.
