[Android] Use platform agnostic tables and merge android specific tables into main scripts

We were using droidMovies in the past; with this change we started using the already existing, cross-platform, IntIdMovies. Since for the Node backend there are no predifined schemas we followed the same serialization that the Managed client tests are using, that is capitalized.
Efforts to have unified cross-platform tests working on both backends are being done separately.
