Summary:
Hi there!
I set up the repo because I want to do a little contribution to the Android side but ran into trouble [running tests](https://facebook.github.io/react-native/docs/contributing.html). The Android environment validation kept failing. While the messages were a little helpful, it would have saved me a bit of time and research if I had some helpful examples to copy-and-paste. In my case, I'm using Android SDK Tools on the command line. Hopefully, this will help others when setting up!
Run `./scripts/run-android-local-unit-tests.sh` with each of the following to see the expanded help messages:
* Make sure `$ANDROID_HOME/platforms/android-$MAJOR` is _not_ present.
* Make sure `$ANDROID_HOME/build-tools/$BUILD_TOOLS_VERSION` is _not_ present.
* Make sure `JAVA_HOME` is _not_ set and/or is _not_ in `PATH`.

Summary:
The goal of this pull request is to make it easier for contributors to run Android tests locally, specifically the unit tests and integration tests. I added a bunch of checks to the local testing scripts that will warn you if your environment is misconfigured, and tell you how to fix it. I also updated the testing docs, so that the regular "Testing" page should be a decent resource to point people to when you are telling them "hey this pull request needs a test." Just Android, though, I haven't gotten to the iOS parts yet.
I also disabled a couple tests that seemed quite flaky while running on a local machine, and don't seem to be providing much value. In particular, the `TestId` test just hangs on my emulator a lot and has been flaky on CI in the past, so I removed about half of its test cases to make the sample app smaller. The testMetions test appears to be dependent on screen size so I commented it out.
