"connect existing account" signup when logged in?

Lines 46 to 47 in 2e4a2bb

	If you didn't see the list of institutions and (social) platforms, you are likely already logged in.
	In this case you can simply select *'SIGN UP'*.

I think this paragraph is not necessary. It makes little sense: if you are already logged in, why should you then sign up?

This is probably related to the UX bug mentioned in #22 (https://ggus.eu/index.php?mode=ticket_info&ticket_id=154418)
When that bug is fixed, use user will probably not see "Sign up" when logged in.

That could indeed be true, but I'm also confused by the EGI UX...
