Add compat for Play Services v15+ (#278)

Adding specific v4 GTM dependency on Android (`com.google.android.gms:play-services-tagmanager-v4-impl`) allows us to use Play Services v15+. This is for better compat with other libs who pin their Play Services-versions higher than this lib.

Have also rewritten examples a bit to test for compat between Gradle-versions. Since RN 0.56+ uses a newer Gradle-version, I have made one RN which is pre-0.56, and one which is post-0.56, and build both in CI (Travis).

Minor fix for `trackEvent` number bridge conversion bug.
