Osc.staging.set_status_report() always returns False

[oSoMoN]

Osc.staging.set_status_report() always returns False because the implementation expects the parsed response object to have a "code" attribute with a value of "ok".

In my tests, SUSE's internal build system returns a check object that doesn't have a "code" attribute. This looks like:

<check name="foo" required="true">
  <state>success</state>
  <short_description>check was successful</short_description>
  <url>http://example.org/</url>
</check>

You gotta love the consistency in the API design 😂
