Title: Always escape the result of link_to_unless method

The return string of link_to_unless method should be always html-escaped to keep consistency.

```ruby
link_to_unless(false, 'Showing'.html_safe, 'github.com')
# => "Showing"

link_to_unless(true, 'Showing'.html_safe, 'github.com')
# => "Showing"

link_to_unless(false, 'Showing', 'github.com')
# => "<b>Showing</b>"

link_to_unless(true, 'Showing', 'github.com')
# => "Showing" should be "<b>Showing</b>"
```
