**ISSUE TYPE** Bug Report **Jenkinsapi VERSION** - 0.3.10 **Jenkins VERSION** - 2.150.3 **SUMMARY** Jenkins API is returning Experiencing an issue while attempting to use the get_changeset_items() method. The relevant lines are here: https://github.com/pycontribs/jenkinsapi/blob/8e9367517083f92ce712fb607ab118e9bf577db5/jenkinsapi/build.py#L142-L144 It appears that `self._data['changeSets']` is a list rather than a dict, so checking if 'items' is in it will not return true. **EXPECTED RESULTS** I'd expect that the method would return the changeset items for the build. **ACTUAL RESULTS** An empty list is returned. **USEFUL INFORMATION** Picture of type returned in the build._data: <img width="441" alt="Screen Shot 2019-11-08 at 2 58 54 PM" src="https://user-images.githubusercontent.com/9022501/68507361-b6b61880-0239-11ea-9408-5bb305c6e3e9.png">
