Add Home URL to New User emails

[Ipstenu]

Back when we all had one website and we jolly well liked it, it was easy to know "Oh someone signed up at my site!" Now that people manage multiple sites, some with similar names, it can be confusing as to which site, exactly, did the new user join.

We can save headaches in this one cool trick ... add the Home URL to the emails.

Can you please add missing slash in home_url() for consistency?

$homeurl = home_url();

Replace to

$homeurl = home_url( '/' );

Done

Sorry for the noise. Adding a call for testing.
