Link error in next matches widget

When adding teams, the protocol “http://” is automatically added to the team link field, but when using the next matches widget, the protocol is duplicated, so I have something like “http://http://link.com”. I’ve removed all references to “http://” in lib/widget.php and then it works as expected. Could you fix this? Thank you
