Fix adding non-ascii attrs to Resource objects error

Due to these lines of code [0] we don't have an opportunity
to add attributes with non-ascii symbols to Resource objects,
but information about it will be in _info dict.

Example of side effect - quota_show command.
Because we don't have such an attr, here [1] it will be added
None value instead of real value [2].

This patch fixes this problem.
