Emails for build results do not properly encode URLs

When receiving an email for a build that ran on a branch with a “#” or any other encoding-required character in the name (such as fix#44-blah-blah), the URL does not get escaped and thus leads to a 404 error.


If a build email was received about the branch fix#44-blah-blah on the repository, it would be formatted
It should be formatted instead, to avoid a 404 error from GitHub.
