Subject: [PATCH] fix(@embark/solidity): fix binding in method call

This commit fixes a bug where it throws while trying to compile solidity
files as it dereferences its `this`.

Unfortunately passing methods as lambda callbacks doesn't correctly
resolve its `this` scope even within fat arrow functions, resulting in
unexpected behaviour where `this` inside lambda is `undefined`.
