[FIX] web_editor: do not delete empty .oe_structure element

If a snippet contains a .oe_structure element inside of it, it allows
the user to drop other snippets in that location. The web_editor
contains code which removes all empty parent of an element being
deleted. This is done so that, for example, when the last col of a
3-col snippet is removed, the whole snippet is removed.

However, there was an exception to this rule which was not considered,
if one of these empty parent is an .oe_structure, it should not be
removed.

Note: the only snippet which does this is the parallax snippet.
