Add dependency in com.android.test module differently

[JakeWharton]

Detect this case and use compile (or more correctly, implementation) instead of androidTestCompile.

Workaround for now:

// TODO workaround for https://github.com/facebook/screenshot-tests-for-android/issues/74
configurations {
  androidTestCompile
  implementation.extendsFrom(androidTestCompile)
}
// TODO move this back up to the top of the file once the above issue is fixed.
apply plugin: 'com.facebook.testing.screenshot'

What is the issue, exactly?

[JakeWharton]

In a test module, the runtime dependency is added to androidTestCompile instead of compile.
