Title: [BUGFIX] The {{link-to}} helper should not transition for target=_blank

I'm a bit uncertain about this change in behaviour, but I couldnt come up with a use case where one would want to open a link in a new window but also transition to that.

That's why I changed the link-to helper to only transition if the target is empty or _self.

Test included.
