[TIMOB-24543] iOS: Module assets not copied to packaged module, additional weird behaviors

Here is the thing: The developer has a native iOS module, creates it with appc ti new -t timodule and finds the "assets" directory in the top directory. You create a "test.js" or place an image in there. When using the (deprecated) build.py, it will encrypt the files and copy the generated ones into /iphone/assets. When using the appc ti build -p ios --build-only command, the directory will not be copied to the zip and the generated "assets" directory is not copied to iphone/assets. If you place the assets in iphone/assets directly, this will still not copy it to the module zip. See the attached module project and use the above comments to check the output. Proposed fixes: - Copy the encrypted assets into the zip file - Do not place the generated "assets" diretory in /iphone (only happening with build.py, so that's fine since it's deprecated).
