Properly fix wiki restore.

ProjectWiki.new() creates a new wiki git repository, so any tries
to bare clone a bundle fail. With this patch we remove the newly
created wiki.git before restoring from the backup bundle.

Version 7.5.3
Added the password reset link in the reset mail.

Since some of our users has reported problems with the link
for password reset in some mailclients, we decided to print
the url in plaintext as well as in the html format.
Removed HTTP-clone button

Removed the button for http-cloning for logged in users,
this his due to us wanting logged in users to clone via ssh.

The ability for http-cloning is still there and used for
public repositories.
