Subject: [PATCH] Working directory fix for googletest submodule update (#2151)

* Working directory fix for submodule update

The git submodule update for googletest must be run from the script's root directory

* Added try-finally block around Push-Location

Great recommendation from @vors!

The edit is a best practice incase the user Ctrl-C's out of the script.

Tested locally by exiting out of:
try { Push-Location C:\Users\; Start-Sleep -Seconds 60 } finally { Pop-Location }
