the demo app crashes with torch init.

Hi,
I succeeded to build your project, and I try to make it work with your demo facedetector e-lab on my mobile phone.
I added the permission to the camera. But when I clicked on a button, the app still crashes.
It stops to the instruction torchandroid.cpp : inittorch(AAssetManager* manager, const char* libpath) : luaopen_landroidprint(L)
I think that is the initialization of L that fails but I don't know why.

PS: What surprised me, is that the variable current_cpath that comes from L, contains some absolute paths from my computer. Is it normal?

I saw the issue #92 (I don't use CUDA)
but I think this issue is already fixed since I don't see the library to remove into the Android.mk or main.lua ?

edit: It misses a return to that function luaopen_landroidprint(L)
(I added a return 0 and now it stops at the function ret = luaL_dobuffer(L, filebytes, size, "main") from the function Java_com_torchandroid_facedemo_CameraClass_initTorch from torchdemo.cpp

Maybe if it's helpfull, I have these log with adb logcat :
