[FIX] web_editor: rte_inline tour succeed on chrome

The rte_inline tour was failing on chrome because jquery selector in
chrome does not like a space in the style selector.
On the other hand, other browsers and phantomjs need the space.
This commit change the selector to find the element on chrome and
friends.
