Jim Cummins 10ad47a711 Fix run-android to execute app on all connected devices
Summary:**EDIT: **

This has been updated to simply fix the `run-android` command so that it runs on all connected devices instead of throwing an error.

**Original PR description:**

This adds a new command to the react-native CLI. When executed this command will install and successfully execute your app on all connected Android devices:

`react-native run-android-all`

Closes #5901

**Note:** I wasn't sure how to approach this API since it seems a bit like a flag, but I didn't see any other flags implemented in the cli so it seems like the current trend is to keep all commands to a single phrase. I am open to changing this if need be.
Closes https://github.com/facebook/react-native/pull/5902
