Reverse slices result in negative size

[bk-equityzen]

search[20:0]

results in -20 as the size sent to ElasticSearch. This can possibly cause an error: RequestError(400, 'search_phase_execution_exception', 'numHits must be > 0; please use TotalHitCountCollector if you just need the total hit count')

Proposed Solution:
The slice function should result in a minimum size of 0

s._extra['size'] = n.stop - (n.start or 0) if n.stop is not None else 10
s._extra['size'] = max(s._extra['size'], 0)
