The Android "ti.cloudpush" module has a hardcoded Google Play Services version reference (ie: "com.google.android.gms.version") that it'll inject into the AndroidManifest.xml file in it's "timodule.xml" file.
This metadata tag needs to be deleted from the "timodule.xml". It is no longer needed since it'll be automatically injected by Titanium 7.0.0's new "ti.playservices" module.
This issue will cause a crash on app startup if the "ti.playerservices" module has been manually added above the "ti.cloudpush" module in the "tiapp.xml" file. This is because the last metadata tag ends up being the one read by the Google Play Services library and it'll throw an exception due to a version mismatch.
