moveWithCollisions and hitTestView with SolidRects and Collision.SHAPE is broken.

`moveWithCollisions` does not impede movement upon a collision. This is because[ the line](https://github.com/korlibs/korge/blob/821a3b09f7ec6978af8e8338b36573ed7958dddd/korge/src/commonMain/kotlin/com/soywiz/korge/view/HitTestable.kt#L147)
```
if (collision.all { it == this || it.hitTestView(char) == null }) {
```
Always resolves as true.

in fact `hitTestView` never resolves as true with 2 views that are obviously colliding.

## Workaround:

```
moveWithHitTestable(walls.toHitTestable(),dx,dy)
```
Works as expected.

Read korge/src/commonMain/kotlin/com/soywiz/korge/view/HitTestable.kt around line 147, then compare moveWithCollisions with the moveWithHitTestable workaround described in the issue. Reproduce the collision using SolidRects and Collision.SHAPE, and consider the work complete when hitTestView detects the collision and movement is impeded as expected.
