It turns out that the fix for static links in 6528985ed breaks
sites where baseURL is not at the domain root, (i.e. the Hugo site
is at http://www.example.com/foo/, not http://www.example.com/).
This is because the link strings passed to absURL and absLangURL
have a leading slash, which Hugo resolves to the domain root. This
commit fixes the problem by removing removing the leading slash
from these strings.
