Remote-Self is now working fine/contact page instead of remote profile when contact is added

* Issue https://github.com/friendica/friendica/issues/971 is solved. "remote-self" now works reliable. Additionally there is an additional value for the "remote-self" setting where the user can define, if the imported post should look like it was forwarded or like a post from that user.
* When a friendica contact is added, the user was directed to the remote profile page. This is very irritating. This is changed so that now the user is directed to the local contact page of the newly added contact.
