Deploy contracts that use libraries

[kenshyx]

Hello, I'm trying to deploy my contracts using the new features found here. After many attempts I'm stuck with this error:

TypeError: Cannot read property 'signatures_to_fabi' of undefined

When I'm using simple contracts there is no issue deploying them. This problem occurs if the contract uses a library.
