On a products category page, there is an element ready to host a heading
but it's not explicitly marked as unremovable so when the user tries to
remove any snippet inside it, the heading host is removed as well. This
fixes it by using the `isUnremovable` utility function instead of simply
checking for the `oe_unremovable` class.
Steps to reproduce the issue this commit fixes:
1. Go into the website module
2. Click "Shop"
3. Click "Furnitures"
4. Click "Edit"
5. Drop a title block in "Drag building blocks here to customize the
header for "Furnitures" category."
6. Click the trash bin on your snippet to remove it.
It doesn't get removed. Well now it does.
