Export trie obfuscation can generate duplicated symbols when empty-labelled nodes exist. #59

I detected the issue when I tried to obfuscate a binary twice. On the second obfuscation MachObfuscator detected duplicated export trie symbols – symbols that were created by the trie obfuscation mechanism.

Following screenshot is a proof, that empty-labelled nodes exist :)
