Schematics: rename to a non-existing dir fails on sync to disk

[Brocco]

🐞 Bug report

Command (mark with an x)

Schematics core

Is this a regression?

No

Description

When using tree.rename where the destination is a directory that does not exist succeeds using dry-run (and testing) but fails when actually syncing to disk

🔬 Minimal Reproduction

I created a repo with the reproduction here

🔥 Exception or Error

no such file or directory

This error is stating that the directory you're attempting to write to does not exist.

🌍 Your Environment

important version: @angular-devkit/schematics v8.3.20

Anything else relevant?
The important piece is that it appears to work just fine in memory, the error occurs when trying to synchronize from the virtual file system to the actual file system.
