What is the current behavior?

When building on windows, the new shell: true option doesn't escape arguments anymore, meaning that any commands that had spaces in their path would not work. This includes npm/adb/avd paths and app paths (that get passed to gradle via arguments)

What is the new behavior?

We now quote every command to preserve the previous behavior.
