[FIX] web_editor: allow adding options on predefined bg classes

The editor allows using background image options on snippets which
use a background-image. For this to work, the oe_img_bg css class
has to be on this snippet. The problem is that the class is absent
when using some themes as the select_class method removes it to place
its own value.

Now, the oe_img_bg class is (re)added when a select_class method is
used within the background image option.
