HTML views render in error starting Splunk 8.0.1 if a Simple xml view has an empty label

[Guilhem Marchand]

If a simple xml view contains an empty tab label:

<label></label>

‌

The Oops page appears and the following message is logged:

  File "/Applications/splunk/lib/python3.7/site-packages/splunk/appserver/mrsparkle/controllers/view.py", line 806, in buildViewTemplate
    viewList.sort(key=lambda x: x['label'])
TypeError: '<' not supported between instances of 'NoneType' and 'str'

This is a Splunk bug.
