Summary:
This diff changes the way views are inserted by the diffing algorithm.
Previously the diffing algorithm inserted views top-down, now it insert views bottom-up (same order as previous version of RN).
Let say we need to create the following tree:
```
A --> B --> C
|
| --> D
```
Before, the diffing algorithm created the following list of instructions:
```
insert(A, B, 0)
insert(B, C, 0)
insert(B, D, 1)
```
After this diff, the insert instructions are going to be:
```
insert(B, C, 0)
insert(B, D, 1)
insert(A, B, 0)
```
