Merge layouts

[gpallas16]

What are the steps to reproduce this issue?

1. Create project A and add some layouts
2. Import project A's aar to project B. All layouts from project A are accessible as expected.
3. Create fat aar with project A and project B
4. Import fat aar to project C. The layouts from project A are not accessible and app crashes if some class from project B uses a layout from project A (which was working normally before the fat aar) . All project B layouts are accessible.

What happens?
The layout files are in .aar/class.jar/res/layout and not in .aar/layout. The R file from project A is missing too. I use minifyEnabled true with no shrinking and no optimizations. I am relatively new to aar so I dont know if this is a bug or I m missing something. Any advice would be nice!

I use gradle 3.2.0 and fat-aar version 2.0.2
