FIX pointless "or" in login/register UI without external auth

Normally, these UIs show a list of external out icon, then the word "or" and
then the builtin e-mail based authentication. However, when all external
authentication providers are disabled, their icons are hidden, but the (now
pointless and confusing) "or" stays. This commit fixes that.
