Eos: print implementation for std::string

[sim31]

If I try to print variable of type std::string I get this compile time error:

In file included from /usr/local/include/eosiolib/vector.hpp:2:

After updating to the eosio.cdt binary for 1.4.0 this error is back. Ubuntu 18.04.1 LTS. Going to try compiling the source to see if the error persists.

use const std::string not std::string as arguments.
