show output raises KeyError

[Peter Razumovsky]

When I try to call output-show command, next error raises:

Decision is update self.outputs with some value.

When exactly does this happen? A sample template and steps to reproduce would be helpful.

    Fix show output with unresolved stack outputs

    When stack initialized with resolve_data equals to
    False, outputs equals to empty dict. So, update stack
    outputs with resolved value.
