Finding element by class name should accept elements with other classes

[jachymb]

A html element may have multiple classes like: <a class="foo bar">. Then when I use browser.find_elements_by_class_name('bar') or similar method the element is not found. I believe it should be.

This is covered already by finding elements by CSS selector:

browser.find_elements_by_css_selector('.bar')
