Fixed bugs in HTML parsing

[TheTechromancer]

This PR addresses two bugs:

1. The google and bing lxml parsers fail to find any matches (the syntax is still correct, so heaven only knows why it stopped working). Resolved by using BeautifulSoup, which still leverages lxml behind the scenes.
2. When the linkedin name parser fails to split on '|', it throws an exception and the entire page of results are lost. Resolved by handling that AttributeError.

Cheers
