React Native debugging is broken after sharing

[lostintangent]

Product and Version [VS/VSCode]: VS Code
OS Version [macOS/Windows]: macOS
Live Share Extension Version: 0.2.58

Steps to reproduce:

1. [Host] Make sure to have the React Native extension installed
2. [Host] Open up a React Native project in VS Code and share it
3. [Host] Press F5 to start debugging

Expected: For the VS Code debugger to launch the app

Actual: An error is displayed

If the host stops sharing and presses F5 again, then debugging works as expected. This is particularly problematic as host debugging is completely broken while sharing.

Closing in favor of #164, which captures the current behavior more accurately.
