View is not attached after restoring from Bundle

[Nublo]

To reproduce we need to have next setup:

|--> MainContainerRIB
|--|--> ChildContainerRIB1
|--|--|--> ChildRib1
|--|--> ChildRIB2

1. Enable Don't keep activities
2. Start with ChildContainerRIB1.ChildRIB1 configuration
3. Push ChildRIB2 configuration
4. Hide/unhide application to trigger saving configuration in Bundle
5. Reopen app
6. Move back to ChildContainerRIB1.
7. ChildRIB1 view is not attached.

Explanation of what is happening:

• Check RoutingStatePool.individual()
• When pushing next configurations we invoke Effect.Individual.PendingDeactivateTrue for ChildRib1 which add this key into pendingDeactivate
• Then we receive Effect.Individual.Deactivated but we do not clear ChildRIB1 key from pendingDeactivate
• When saving state into Bundle we have a logic which checks pendingDeactivate and moves it to the INACTIVE state.

com.badoo.ribs.routing.state.feature.state.WorkingState.toSavedState()
...
!pendingDeactivate.contains(entry.key) -> original
   else -> original.withActivationState(
      activationState = RoutingContext.ActivationState.INACTIVE
)
...

• After restoring that Node is moved to INACTIVE state and then is never becomes activated.
• Activating is responsibility of WakeUpAction which activates only SLEEPING nodes.

Solution proposed is to cleanup pendingDeactivate and pendingRemoval when receiving Removed|Activated|Deactivated effects.
