ensure host ends in a slash

[jphager2]

Also updated specs that check equality of host or host + path to expect
trailing slash for host.

This is in reference to #236.

@kjvarga anything I should do for this pull request?

[kjvarga]

Please rename append_slash

Sorry to take so long. I've commented.

Hi @kjvarga, I can revert the changes to the specs, but the problem will be that all specs that test #host will return host with a slash at the end. Which means that many of the specs will fail their expectation.

So any further thoughts on this, @kjvarga?

I came back to this. I wasn't happy with modifying the host, and thought to rather just ensure a slash is present when the url is constructed. But I can't reproduce an error. The sitemaps_path portion will only be missing from the URI.join if it's present and doesn't end in a slash, but code already exists to ensure it ends in a slash.

Are you able to provide me an example where it fails? I can't reproduce.
