Metasploit listeners do not work

[Sunderw3k]

When the agent executes any metasploit payload, it hangs until it ends, which does NOT work for exploit/multi/handler.

@Sunderw3k actually was looking at that problem on my own branch, managed to fix it.
It's due to the execution flow of metasploit, doesn't solve the session correct.
