This PR fixes #24222, previously fixed in #24313 but reverted by broken test.
hscan, zscan, sscan problem on phpredis that it can't iterate sets with cursor still occurs 6.x, 7.x branch so I requested this pr. If something is wrong with pull request process, please let me know.
This PR fixes *scan methods for phpredis and add missing *scan tests to redis connection.
Current Behaviour
Redis Facade set phpredis as client returns no cursor with same results on every *scan call. So it can not iterate sets that has many members.
Fixed Behaviour
Returns cursor with results on *scan methods for phpredis. This behaviour is compatible with predis adapter.
It can iterate over sets until all member has been returned.
