Do not use icon for "WikiLove" link when it is inside the "More" dropdown
Do not use icon for "WikiLove" link when it is inside the "More" dropdown

This is the same idea as the patch in Vector for the "Watch" icon:
8db5779682cb6579c49d9a8cca2afcccdc6128a4.

The "icon" CSS class is only added to the tab in the Vector skin (see
WikiLoveHooks::showIcon()), so we can use the 'vectorTabs' class here.
