You need to specify constantconstant so that you get the return value of a call:

function get_from_map(uint _key) constant returns (address).

You need to specify constant so that you get the return value of a call:

function get_from_map(uint _key) constant returns (address).

Without constant, test.get_from_map(1) is a sendTransaction which always returns a transaction hash. See What is the difference between a transaction and a call?
