Fix to facilitate old LinkedIn URL

Some people still have their LinkedIn URL in the old fashion.
That is, instead of having a username-based URL i.e `http://linkedin.com/in/username`, their url is still `http://linkedin.com/pub/firstname-lastname/some-random-character/etc`

For example: `https://www.linkedin.com/pub/greg-street/7/644/b35` or 
my old linkedin url before I modify it: `https://www.linkedin.com/pub/fadil-sutomo/10/8aa/a5b`

In summary, the current format of simply supplying LinkedIn username might not work for some people
