 preview_sidebars_widgets unsets $sidebars_widgets['array_version'] without
 checking that it is ever set in the first place.

 Granted that it should be, however if a developer wants to remove all
 widgets from their site, it is possible that they will clear them from a
 database, a database may be corrupted, or a plugin/theme sets this option
 by mistake.

 Suggest that this should have a conditional check to ensure that
 $sidebars_widgets['array_version'] is actually set and also ensure that
 this function always returns an array, even if the database has been
 emptied.
