update opt for renamed formula

Browse Source 
After the formula gets renamed oldname opt is created and
it points to the linked keg. However if we then upgrade newname
oldname opt still points to the same keg it pointed before upgrade.
The commit fixes this behaviour thus that oldname opt links at the
same keg opt point.
