CollectionSuppliers.objectArraySupplier is never called

[garcia-jj]

The method is here: https://github.com/rafaeldff/Iogi/blob/master/src/br/com/caelum/iogi/EmptyObjectsProvider.java#L84

This method is never called, because when we have a empty object array, EmptyObjectsProvider.provide is catched by target.getClassType().isArray().

https://github.com/rafaeldff/Iogi/blob/master/src/br/com/caelum/iogi/EmptyObjectsProvider.java#L46

Since this method is never used, can be removed.
