Fix broken datastore test_cursor_paging. (GoogleCloudPlatform#1457)

SurferJeffAtGoogle · Jon Wayne Parrott · commit d9c5a10e4167 · 2018-04-17T09:44:55.000-07:00
When there are only 6 entities being retrieved, and the page size is 5,
then the second page will not have a next cursor because all entities
have been retrieved.

Also, ignore *sponge_log.xml which are test log files.
