Remove 'empty' as an option as a spec result

- Having the 'empty' state for a spec result can be considered a
breaking change to the reporter interface
- Instead, we determine if a spec has no expectations using the added
key of 'passedExpectations' in combination of the 'failedExpectations'
to determine that there a spec is 'empty'
