Fix to memory leak leaving WallpaperCropActivity.

After running wallpaper cropper serveral times it crashes with
an OutOfMemotyException.

When leaving WallpaperCropActivity all textures are leaking until end
of process lifetime. This is due to a missing call to function
TiledImageView.destroy which in turn assures TiledImageRenderer
releases held resources.

Resolved by assuring WallpaperCropActivity calls TiledImageView.destroy
from WallpaperCropActivity.onDestroy. In case where onDestroy is not
called resources will be released anyway by process being brought down.

NULL previous background bitmap upon changing wallpaper

Step to reproduce it on Nexus 10 with 4.4.2(KOT49H):
1. Long press on home screen.
2. Choose wallpaper from Wallpapers.
3. Select new wallpaper and set it.
4. Repeat step 1-3 several times.
See black background instead of the wallpaper.

There are two binder objects who hold reference to the
ImageWallpaper$DrawableEngine, which keeps the big chunk
bitmap from being recycled.
One is WallpaperService$IWallpaperEngineWrapper. The client
references went away slowly, maybe several minutes after
changing wallpaper. Then the finalizer has to been executed
to GC it.
The other one is WallpaperService$Engine$BaseIWindow. Don't
know who still held reference to it even after the window
was removed.
Anyway, let the bitmap be GCed first.
