Jakub Libosvar 9b03e71707 Fix H302 violations in unit tests 
H302 violation is reported by flake8 when importing separated objects from
modules instead of importing the whole module.
e.g.   from package.module import function
       function()
is changed to
       from package import module
       module.function()
