[Fix-563] Switch: UserInteraction bug

[robergro]

One developer on Polaris found this problem on the switch:

1. Init the switch with isOn to false (or true)
2. set directly the isOn to a different value true (or false)

-> the switch userInteraction is disabled.

Why:
The userInteraction is always set to false before update the space position inside the toggle and reset to the old value when the animation is finished. But if a new value is set before the completion of the previous animation, the bug appears.

Solution:

• get the current userInteraction from the viewModel and not from the UIView
