This commit fixes the issue of adding single-span items in between full-span items whilst using `StaggeredGridLayoutManager` on recycler view.

Adding such items results in:
```
java.lang.ArrayIndexOutOfBoundsException: Array index out of range: 13

	...and more
```

Affects versions including and prior to androidx.recyclerview:recyclerview:1.2.0-alpha02 (at the time of this commit) and possibly more after that.

This bug is caused by a single fact and that is - array inside of `LazySpanLookup` is not being invalidated and resized correctly when non-full-span item is being added in between of two full-span items. The invalidation however passes on some (high performance) devices so it doesn't necessarily cause issues for _some_ users; others keep getting the same crash over and over again.

Possible fix for anyone reading this, in the hope of fixing the same error, is to copy-paste the `StaggeredGridLayoutManager` and fix the array length before calling `Arrays.fill()`. There's no fix from user's perspective if you need to keep the UI as-is.
We however don't need the UI as-is, so we're instead opting to use LinearLayoutManager until is the issue resolved.
