Python3 unit tests

[matusvalo]

This branch fixes issues with unittests and now all unittests are passing (in python3 and python 2.7) - see below. Moreover one issue is fixed found by unittests - conneciton._declare_queue() was returning bytes instead of string in python3.

[auvipy]

seems ok to me. do you have any other inputs?

For now not. Maybe later I will add more unittest but for now python 3 migration should be done. If new issues will pop out I will fix them.
