In xml when parent node (`restaurants`) contains several children nodes with the same tag (`restaurant`) it is clear that the children form a collection:
```
restaurants = {array} [1]
restaurant = {array} [2]
0 = {array} [2]
name = "Some restaurant name"
type = "Chinese"
1 = {array} [2]
name = "Another restaurant name"
type = "Italian"
```
Afterwards the object denormalizer has no problem to create a collection of restaurants.
But when there is only one child (`restaurant`) the decoded normalized array will not contain a collection:
```
restaurants = {array} [1]
restaurant = {array} [2]
name = "Some restaurant name"
type = "Chinese"
```
In this situation the object denormalizer threw unexpected exception. This PR modifies `AbstractObjectNormalizer` that is it will fill a collection containing the sole element properly.
