Regenerated sample dump.rdb using Redis 2.8
Regenerated sample dump.rdb using Redis 2.8

It was previously generated using a Redis 3.2 instance, and there was a
forward-incompatible change in the .rdb dump format between 3.0 and 3.2.

This commit rules out version incompatibilities when running tests with
a Redis 2.8 instance.
