Changes logic of invalidation in RedisTagAwareAdapter in order to:
- Delete the tag key on invalidation => _avoiding possible left behind empty tag keys that Redis is not allowed to evict, gradually consuming more and more memory_
Positive side effects of no longer using sPOP:
- Lowered requirements to Redis 2.8, and no specific version constraint for phpredis
- Lift limitation of 2 billion keys per tag _(Now only limited by Redis Set datatype: 4 billion)_
