Description:
Virtual Scroll component not being destroyed when being presented inside a Modal.

Expectation:
Proper deletion and un-referencing of component

Steps to reproduce:

1. Take a heap snapshot to compare with.
2. Open a modal with a Virtual Scroll component inside the modal.
3. Dismiss the modal. *repeat steps 2 & 3 a few times
4. Take a Heap Snapshot and compare with your first and realize the additional Virtual Scroll Components that remain in memory.

I've been struggling to find the root cause of this issue and have failed to find a fix for it.. So before I head home for the day, I've chosen to let the community and DriftyCo to take a crack at it.
